House Speaker Nancy Pelosi slammed President Donald Trump's decision to call off coronavirus relief talks, saying he's "unwilling to crush the virus" and is "putting himself first at the expense of the country."

"Today, once again, President Trump showed his true colors: putting himself first at the expense of the country, with the full complicity of the GOP Members of Congress," Pelosi said in a statement Tuesday afternoon.

"Walking away from coronavirus talks demonstrates that President Trump is unwilling to crush the virus, as is required by the Heroes Act.  He shows his contempt for science, his disdain for our heroes – in health care, first responders, sanitation, transportation, food workers, teachers, teachers, teachers and others – and he refuses to put money in workers' pockets, unless his name is printed on the check," she added. — Yun Li

President Donald Trump just informed Americans that the White House would stop negotiating a second stimulus package until after the November election and stocks are tanking. 

CNBC Pro asked the Pros about Trump's strategy and how to play it in the market. 

"Maybe spending this money isn't as important to [Trump]. Maybe he feels that the economy can stand on its own two feet without another $2 trillion of government spending," Peter Boockvar, Chief Investment Officer at Bleakley Advisory Group, told CNBC. "This comes in the context of Congress that's already spent $3 trillion and there's still a wide gap between what the Republicans are willing to spend, $1.6 trillion, and what the Democrats want to spend at $2.2 trillion."

"At least for now I'm believing that this is part of a negotiation rather than something that's firm," added Boockvar. "Both sides don't like each other. Both sides don't want to give an inch to the other side."

Federal Reserve Chairman Jerome Powell said he and his colleagues knew they'd come under criticism for their actions in the early days of the economic shutdown but felt they needed to do everything they could. Powell said Fed officials decided "we needed to use all of our tools and needed to do so in maybe ways where there'd been red lines saying we won't cross those red lines." Specifically, he said the Fed's facilities to buy corporate debt went beyond what previous Feds had done to help the economy in times of crisis. "I think history will judge how well we did. I have never regretted the fact that we did that," Powell told the National Association for Business Economics. — Jeff Cox

The manufacturer forecast on Tuesday that the world's airlines will need 18,350 planes worth $2.9 trillion over the next 10 years, an 11% drop from its forecast a year ago and a jarring downbeat prediction after years of strong growth in travel around the world.

Shares of Boeing last traded about 1.4% lower.

Federal Reserve Chairman Jerome Powell provides his outlook on the economy Tuesday morning when he speaks to a virtual gathering of the National Association for Business Economics. The official topic for the central bank leader's presentation is "Global Reset? Economics, Business and Policy in the Pandemic." In addition to providing prepared remarks, Powell will exchange in a question-and-answer session with a moderator. The chairman's views often can move markets. At their last meeting, in September, Fed officials officially adapted a new approach to inflation in which they effectively pledged not to raise interest rates even if the jobless rate falls below what has traditionally been considered full employment. The officials also adjusted their economic projections, taking a bit more optimistic view of growth in 2020 but reducing the outlook for the next few years. — Jeff Cox

Shares of SeaWorld Entertainment rose more than 4% in the premarket after an analyst at Credit Suisse upgraded them to outperform from neutral. The analyst also hiked his price target on the stock to $30 per share from $13 per share, implying a 46% upside from Monday's close.

Originally, "there were three concerns that made us cautious," said analyst Benjamin Chaiken in a note, referring to: "(1) impact from Epic Universe in Orlando, (2) a cost structure that looked fully optimized, or close to it, and (3) high leverage to Orlando."

"Since the COVID-19 outbreak, we believe the data points surrounding those headwinds have either changed or are now fully priced in, making us more constructive on a stock with relatively low expectations," Chaiken said.

SeaWorld shares are down more than 35% year to date. However, they have surged 95.8% over the past six months. —Fred Imbert

Moderna's Covid-19 vaccine trial has slowed after the company failed to attract enough Black, Latino and Native American participants, according to Reuters. As of Sept. 17 roughly 7% of the 30,000 participants were Black Americans, a number that should have been closer to 13%, Reuters said citing those familiar with the matter.

Shares of Moderna were about 1% higher during premarket trading on Tuesday. The stock is up more than 260% this year. - Pippa Stevens

Treasury yields continue to push higher in early trading, as markets eye the possibility of a massive stimulus package.

The sell-off in Treasurys Monday triggered a big move in yields, which rise as investors dump bonds.

BMO says the 10-year's move to 0.782% was its third run at that support level since mid-July. The 10-year yield, which moves opposite price, was on both sides of that level in Tuesday trading.

"The risk-on price action in other markets certainty contributed to the selloff in Treasuries, as did the effort to price in an auction concession for this week's 10- and 30-year supply," BMO strategists note. "What remains to be seen is whether US rates have established an interim floor in the wake of the overnight bid, or if 78.2 bp in 10s is too strong of support to fade at this stage."

The bond market is also awaiting Fed Chairman Jerome Powell, who speaks at NABE later this morning. —Patti Domm
