With many states reopening for business, sobering estimates about the potential spread of Covid-19 in the U.S. are emerging. Former FDA chief Dr. Scott Gottlieb said the U.S. will see an increase of Covid-19 cases and hospitalizations in May as business restrictions across the country are lifted. "We don't know how much, but they're not going to go down," Gottlieb said.

The baggage handlers' union that represents United Airlines sued the airline over schedule cuts, claiming it violated the terms of billions in federal coronavirus aid.

At least two U.S. senators criticized airlines for cutting workers hours after they received federal coronavirus aid. 

"The assistance provided to air carriers in the CARES Act was conditioned on protecting airline workers from layoffs and furloughs," Sen. Sherrod Brown (D-Ohio) told CNBC in a statement. "The Administration needs to do more to make sure airlines are using the payroll support funding as intended, and not to cut workers hours and benefits." —Leslie Josephs

U.S. hospitals have seen revenues flatline during the pandemic after they had to delay non-emergency medical procedures during the spring. Conservative estimates indicate that hospitals in the U.S. are losing more than a billion dollars per day by complying with the guidance

According to the American Hospital Association, hospitals are bleeding more than $50 billion per month. Private equity investor and public policy professor Meghan Fitzgerald, estimates through her own research that it's about $1 to $1.2 billion per day. "Many of these procedures were medically necessary, and -- yes -- profitable, enabling these institutions to serve all patients," she said. —Christina Farr

6:58 pm: President Trump tours respirator facility without wearing protective mask that workers are required to wear

U.S. President Donald Trump looks at a protective face mask being shown to him by Honeywell's Vice President of Integrated Supply Chain Tony Stallings as he watches workers on the assembly line with White House Chief of Staff Mark Meadows while touring Honeywell's facility manufacturing masks for the coronavirus disease (COVID-19) outbreak in Phoenix, Arizona, May 5, 2020.

He got a mask, but didn't wear one.

President Donald Trump didn't put on a mask to tour an Arizona factory that makes N95 respirator masks for the government's coronavirus response, and where workers are reminded by a sign that they need to wear protective facial covering during their shifts.

The White House said officials at factory operator Honeywell told them that Trump and other guests would not have to wear masks during their tour Tuesday of the Phoenix facility.

Trump, who earlier said he would wear a mask if they were required, walked around the factory floor as the song "Live and Let Die" played from speakers. 

He was later presented with a gift, an N95 mask mounted on a plaque. —Dan Mangan

Texas Gov. Greg Abbott announced that the state's hair and nail salons, barber shops and tanning salons will be allowed to reopen starting this Friday while adhering to health guidelines set forth by the state. He said that customers at these businesses must maintain six feet distance and will be required to wear a face mask, among other modifications the state plans to set forth.

Abbott said that on May 18, gyms will also be allowed to reopen at 25% occupancy as long as showers and locker rooms remain closed. He said that equipment will need to be sanitized after every use and gym-goers will be required to wear gloves, and any outside equipment must be sanitized before and after entrance. The Texas governor previously allowed some businesses, like retail stores and movie theaters, to reopen on Friday as long as they maintained 25% capacity as part of the state's phase one reopening plan. —Noah Higgins-Dunn

The Shanghai Disneyland will reopen its doors on May 11. It has been closed since January 25 due to the global Covid-19 outbreak.

Already open in Shanghai is the shopping center Disneytown, Wishing Star Park and the Disneyland Hotel. The company will take a phased approach in reopening this park. It will limit attendance, implement new social distancing practices and integrate more sanitation stations throughout the park. It is currently unclear when the rest of Disney's parks, resorts, cruise ships and Disney-branded stores will be able to reopen. —Sarah Whitten

5 pm: Trump says coronavirus 'bailouts' for blue states are unfair to Republicans 

Using federal funds to help states recover from coronavirus is unfair to Republicans, said President Donald Trump, "because all the states that need help — they're run by Democrats in every case." 

In an interview with The New York Post, Trump said that Illinois, New York and California are examples of states with "tremendous debt," while Florida and Texas are both "doing phenomenal" and the Midwest is, "fantastic — very little debt."

As Congress prepares to hammer out a fourth coronavirus aid package, and governors in both parties clamor for more funds, the question of what requirements will be placed on additional federal money for states is emerging as a key fault line. 

On Tuesday, Trump tweeted that "Sanctuary Cities, Payroll Taxes, and perhaps Capital Gains Taxes, must be put on the table." —Christina Wilkie

California Gov. Gavin Newsom announced that the cities of Huntington Beach, Dana Point and Seal Beach are allowed to begin a phased reopening of their beaches after the cities submitted plans to allow safe public access to beachgoers.

The plans include a range of measures to avoid overcrowding and enable safe physical distancing on the beach, according to a press release from the California Natural Resources Agency.

Newsom said he would allow Laguna and San Clemente beaches to reopen on Monday.Newsom ordered the beaches in Orange County to close on Thursday after the crowds of people congregated on the state's coasts over the weekend. Newsom said beaches in the southern part of California, including those in Orange, Los Angeles, and San Diego counties, have raised alarm bells, saying beachgoers have failed to follow physical distancing guidelines. Officials in Orange County criticized Newsom's order, however, for unfairly targeting the county. —

3:19 pm: White House could phase out coronavirus task force by early June

The White House coronavirus task force could soon be history.

Vice President Mike Pence, who oversees the task force, confirmed in a meeting with reporters, that the administration is considering phasing out the group, possibly as soon as early June, 

The slow phase-out would involve transitioning the country's Covid-19 response to other federal agencies, and would coincide with the easing of lockdown restrictions in several states.

Response coordinator Dr. Deborah Birx and National Institute of Allergy and Infectious Diseases Director Dr. Anthony Fauci had been stars of the task force's near-daily press briefings, but have already moved somewhat out of the spotlight. The on-camera briefings haven't been held since April 24. Read more on the possible transition from CNBC's Kayla Tausche and Kevin Breuninger—Sara Salinas, Valerie Block

Cuomo said New York and other Democratic-led states have paid more in federal taxes than they've received, and sharply criticized what he called partisan rhetoric coming from Trump and Senate Majority Leader Mitch McConnell, R-Ky., in a time of crisis.

"This coronavirus doesn't pick Democrats or Republicans. It doesn't kill Democrats or Republicans, it kills Americans," Cuomo said at his daily press briefing. —Kevin Breuninger

1:55 pm: Researchers say the virus has mutated and looks more contagious

The coronavirus has mutated and the new strain spreading across the United States and other parts of the world appears to be even more contagious, according to new research published by scientists at the Los Alamos National Laboratory.

The Los Alamos researchers were able to analyze thousands of coronavirus sequences collected by the Global Initiative for Sharing All Influenza. They said the new strain began spreading in Europe in early February before migrating to other parts of the world, becoming the dominant form of the virus across the globe by the end of March.

If the virus doesn't subside in the summer like the seasonal flu, it could mutate further and potentially limit the effectiveness of the vaccines currently being developed by scientists around the world, the researchers warned. —Berkeley Lovelace Jr. 

1:36 pm: Five European countries still not seeing drops in the number of new cases

Most European countries are reporting decreases in the daily number of new Covid-19 cases, but the United Kingdom, Sweden, Poland, Romania and Bulgaria are not seeing a decline, CNBC's Holly Ellyatt reports.

The number of new cases was increasing in Bulgaria, and in the other four countries, there was "no substantial change" in a key measure of the prevalence of active coronavirus cases in the population, according to the European Centre for Disease Control and Prevention (ECDC).

Sweden, notably, did not impose a full lockdown but encouraged people to work from home and limit contact with vulnerable groups. Sweden has confirmed 23,216 cases and 2,854 deaths, according to data from Johns Hopkins University. —Chris Eudaily

1:07 pm: President Trump says he will wear a mask on factory tour, if required

President Donald Trump, who has for weeks refused to wear a mask as a coronavirus precaution despite federal guidance urging Americans to do so, might wear one during a visit to a mask-production factory in Arizona — but only if he's required to do so.

Trump is set to tour the Honeywell facility in Phoenix, which is making N95 masks for the federal government.
"I think it's a masked facility," Trump told reporters. "If it's a masked facility, I will" wear a mask, he said.

Vice President Mike Pence ignited a furor last week by not wearing a mask at the Mayo Clinic, which requires masks for all visitors, patients and staff. Pence wore a mask two days later during a tour of a General Motors plant in Indiana. —Dan Mangan

Nordstrom is preparing to reopen its department stores amid the coronavirus pandemic. Its locations across the country have been temporarily shut since March 17.

The retailer has a number of precautionary measures it will be taking, including adding plexiglass dividers at cash registers to protect workers, handing out masks to visitors, leaving some of its restaurants closed and limiting services such as alterations.

Nordstrom said it will be opening its stores in phases. It remains unclear exactly which shops will open first, and on which dates. The retailer's plans follow those that Macy's laid out last week as it prepared to open 68 locations Monday. —Lauren Thomas

12:33 pm: Trump says Dr. Fauci was blocked from testifying at Covid-19 hearing 'because the House is a set up'

The White House stopped Dr. Anthony Fauci from testifying at a House hearing on the U.S. coronavirus response because the Democratic-held chamber is full of "haters," President Donald Trump said.

The president's explanation, which indicates political motivations behind blocking the key health official from appearing Wednesday, contradicts one the White House offered on Friday. Administration spokesman Judd Deere said it would be "counter-productive" for the director of the National Institute of Allergy and Infectious Diseases to testify while he works on the government pandemic response.

Trump offered a different reason Tuesday.

"Because the House is a set up," he told reporters when asked why the White House blocked Fauci from appearing Wednesday. "The House is a bunch of Trump haters. They put every Trump hater on the committee, the same old stuff."

The White House declined to comment on the contradiction between its explanation and the one Trump outlined. —Jacob Pramuk

In the latest CNBC|SurveyMonkey Small Business Survey, 38% of small business owners said they expect changes in government regulations to have a negative effect on their business in the next 12 months. That is the highest that value has been in the three-plus years of the survey, which reaches more than 2,000 small business owners in the U.S. every quarter.

New York City Mayor Bill de Blasio calls President Trump a 'pure hypocrite'

New York City Mayor Bill de Blasio criticized President Donald Trump's comments in a New York Post interview that indicated he would not be inclined to bail out states, especially those run by Democrats, that have financially struggled amid the coronavirus crisis.

De Blasio said Trump was a "pure hypocrite" to not provide financial assistance to states even though he was willing to grant nearly $58 billion to bail out the airline industry.

"That means he's not inclined to help firefighters, EMTs, paramedics, police officers, doctors, nurses, health-care workers, teachers, sanitation workers," de Blasio said at his daily press briefing.

The mayor has projected that Covid-19 will cost New York City a projected $7.4 billion in lost tax revenue over the current and next fiscal year after the city shuttered businesses and ordered people to stay indoors to try to contain the outbreak. —Noah Higgins-Dunn

As food supply chains struggle to keep up with demand amid the Covid-19 outbreak, CNBC's Amelia Lucas reports that nearly a fifth of Wendy's U.S. restaurants have run out of beef, according to a study by Stephens Inc.

The study found that nationwide 1,043 restaurants — or 18% of its U.S. restaurants — have listed beef items as out of stock, though more than 100 locations still sell Wendy's chili, which contains beef, Stephens analyst James Rutherford said.

Many restaurants in Ohio, Michigan, Tennessee and New York restaurants are currently out of beef, while other states' menus do not suggest there are any supply chain issues. —Terri Cullen

10:40 am: When will we start traveling again? Here's what experts say

CNBC's Christina Farr asked experts in public health and various industries for their best predictions on when will we start traveling again. All agreed that it would take around 18 to 24 months before there's a significant spike in demand and the industry begins to return to normal levels.

Air travel has dropped by more than 95%, with some days seeing fewer than 100,000 air travelers across the country. In April 2019, more than 2 million travelers passed through U.S. airports every day.

The experts said the travel industry will undergo some very big changes: Airports may institute new kinds of security checks to screen travelers' health, nervous tourists could opt for 'staycation' destinations, and the travel experience will be dominated by large chains as small hotels and restaurants struggle to survive. –Melodie Warner

10:33 am: US services sector suffers biggest contraction since 2009

The U.S. services sector contracted for the first time in about a decade in April as economic activity in the country ground to a near halt amid the pandemic, the Institute for Supply Management reported.

The ISM nonmanufacturing index plunged to 41.8 in April from 52.5 a month earlier — the first contraction in services since the financial crisis, CNBC's Fred Imbert reports. It was the lowest amount of business activity in the services sector since ISM launched the index in 1997. Still, the April reading topped a Dow Jones estimate of 40. —Terri Cullen

"I know how important it is for so many students and teachers to finish out the school year, and I was holding out hope – particularly for high school seniors – that we'd at least be able to complete the final few weeks, but given the current circumstances and to protect everyone's safety, it has become clear that it's just not possible," Gov.

9:57 am: Groceries have gotten pricier during the pandemic 

It's not your imagination: Grocery staples from milk and eggs to produce have gotten more expensive in recent weeks. Milk prices are up 10%, year to date. Produce prices are up 10%. And egg prices are up 30%. That's all according to research by Nielsen.

In an interview with CNBC's Jane Wells, Nielsen managing director Morgan Seybert said grocers have pulled back significantly on sales. He said in an average week, about a third of products sold by a grocery store is on promotion – but that's dropped to about 20%.

"We've seen a huge reduction in the amount of promotions that retailers are running as they're just trying to get the product and the supply that they need onto the shelf," he said. —Melissa Repko

Gottlieb's comments on "Squawk Box" came after New York City health officials warned Monday of an inflammatory disease, so far impacting 15 children, that could possibly be associated with Covid-19. The condition is characterized by persistent fever and was likened to Kawasaki disease and toxic shock syndrome.

The World Health Organization said it is "not surprising" that reports have emerged of Covid-19 circulating in France as early as December, Reuters reported. China officially alerted the WHO to its outbreak on Dec. 31, though cases were circulating before then as officials in the country sought to identify the mysterious virus.

A hospital in France retested old samples from pneumonia patients and discovered the presence of the virus that causes Covid-19 in one patient, who was treated as early as Dec. 27, according to Reuters. The French government would not confirm its first case of Covid-19 for nearly a month. 

"It's also possible there are more early cases to be found," WHO spokesman Christian Lindmeier told a U.N. briefing in Geneva. He encouraged other countries to investigate whether the virus was circulating earlier than was previously known in order to identify a "new and clearer picture" of the outbreak. —Will Feuer
