Donald Trump won't be shunned by CEOs, experts say

Will CEOs support Donald Trump?

Media mogul Barry Diller may think Donald Trump is evil, but don't expect the presumptive Republican presidential nominee to be shunned by CEOs if he lands in the White House, two experts predicted Thursday.

"People will adapt and find ways to work with him. Some CEOs will support him, some won't. I don't see him being ostracized somehow as inappropriate by a big group of CEOs out there," Harvard Business Review Editor-in-Chief Adi Ignatius said in an interview with CNBC's "Power Lunch."

"CEOs don't have much of a choice. If it happens to be a President Trump, they're going to have to deal with him," added Sydney Finkelstein, a professor at Dartmouth's Tuck School of Business and author of "Superbosses."

Trump has been outspoken against some businesses.

While leaders may like his call for lowering the corporate tax rate, his policies on China will have advocates and detractors, Ignatius said.

However, "this is early stages for what in the world Donald Trump actually believes in," he noted.

Trump won Indiana's primary on Tuesday, prompting his remaining opponents, Texas Sen. Ted Cruz and Ohio Gov. John Kasich to suspend their campaigns.

Barry Diller, chairman and senior executive of IAC and Expedia, had harsh words about the billionaire on Thursday's "Squawk on the Street."

"There's nobody that I've ever known, ever, that's risen to the presidency that was actually of evil character," he said. "Anybody who attacks people in the manner that he attacks people … that's evil."

However, Home Depot co-founder Ken Langone doesn't seem concerned about a President Trump.

"I think he's going to be the president. And whoever he has around him, is going to be people who are going to help him get things done," he told "Closing Bell" on Wednesday.

Conservatives ready to back Trump?

Trump may also have a problem with conservative support. Former Presidents George H.W. Bush and George W. Bush have announced they are sitting out the election season instead of endorsing the Republican nominee.

Jimmy Pethokoukis, fellow at the American Enterprise Institute and a CNBC contributor, believes those who hold office and make money off the Republican Party will mostly back Trump.

"I think there are going to be very large defections among conservatives. I don't know about inside the beltway, but in the rest of the country," he told "Power Lunch" on Thursday.

Avik Roy, a senior fellow at the Manhattan Institute, believes many donors will shift their focus to Senate candidates.

"Republican-aligned donors are really concerned about making sure that they can preserve and protect that Senate majority," he told the show. "They might walk out of the presidential election and focus more on Congress."
