But last week seemed to be a breaking point. Big business could evidently tolerate working with Mr. Trump despite his chauvinism, his flirtations with white nationalism and his claims of impunity, but the president’s apparent willingness to undermine democracy itself appeared to be a step too far.
“This thing was a little different. I mean, we had sedition and insurrection in D.C.,” said Jamie Dimon, the chief executive of JPMorgan Chase. “No C.E.O. I know condones that in any way shape or form. We shouldn’t have someone, you know, gassing up a mob.”
The fallout has been swift. After the president exhorted his supporters to march on the Capitol, chief executives used their strongest language to date to repudiate Mr. Trump, and some of his longtime allies have walked away. Ken Langone, the billionaire co-founder of Home Depot and an ardent supporter of the president, renounced Mr. Trump, telling CNBC, “I feel betrayed.”
Twitter, Facebook and YouTube have banned or suspended Mr. Trump’s accounts. Amazon, Apple and Google have cut ties with Parler, a messaging app popular among his supporters.
Charles Schwab, the brokerage firm founded by a Republican who supported Mr. Trump, said it would shut down its political action committee altogether. And many companies, along with the U.S. Chamber of Commerce, have sought to punish Mr. Trump’s supporters in Congress by depriving them of crucial funds.
“For those members of Congress that were involved in helping to incite the riot, and support the riot, there’s going to be consequences, no question about it,” said Ed Bastian, chief executive of Delta Air Lines.
