Under Armour founder and CEO Kevin Plank set off a social media firestorm last February when he voiced some overly positive words about the new administration of President Trump.
"To have such a pro-business president is something that's a real asset for this country. I think people should really grab that opportunity," said Plank, whose company makes sports apparel.
On Monday, Plank became the latest corporate CEO to publicly cut ties with the president, giving up his seat on a White House advisory council on manufacturing amid criticism over the president's response to the violence in Charlottesville, Va., last weekend.
"There is no place for racism or discrimination in this world," Plank said in a tweet.
Others quitting the council are Merck's Kenneth Frazier and Intel's Brian Krzanich. Scott Paul, president of the Alliance for American Manufacturing, an industry group, also announced his departure Tuesday, tweeting, "I'm resigning from the Manufacturing Jobs Initiative because it's the right thing for me to do."
And AFL-CIO President Richard Trumka also stepped down from the council.
"I think these leaders are waking up to the fact their continued silence in the face of mounting evidence of immorality is tantamount to consent," said Nicholas Pearce, clinical associate professor of management and organizations at Northwestern University's Kellogg School of Management.
The departures underscore the dilemma facing corporate chief executives at a highly polarized and partisan time, said David Ulrich, professor of business at the University of Michigan's Ross School of Business and a partner at the consulting firm RBL Group.
They may share Trump's pro-business agenda, but find it difficult to ignore his personal behavior, Ulrich said.
"How do you begin to manage the balance between the person and the policy? And I can imagine these CEOs are really struggling to find that right balance between those two things," Ulrich said.
He noted that corporations have a big stake in policy decisions being made right now, and giving up a seat at the table means having much less influence in Washington.
"It's pretty easy for a CEO to say, 'These are my values. You violated them.' But the CEOs who are smart know, 'Once I back out of that opportunity to shape policy, the voice that I could have had is now lost,' " he added.
Trump insisted Tuesday that he would have no trouble replacing the departed members of the advisory council and dismissed them as "grandstanders."
And some high-profile companies have said they are staying on the council.
"We must engage if we hope to change the world and those who lead it," said Alex Gorsky, chief executive of Johnson & Johnson, in a statement released Tuesday.
"Our commitment to diversity and inclusion is unwavering, and we will remain active champions for these efforts," said a spokesman for Campbell Soup CEO Denise Morrison.
The decision to leave is harder for some companies than others.
Among those staying on the council are the CEOs of several major companies that have substantial federal government contracts, including Lockheed Martin and United Technologies.
Given Trump's tendency to hit back hard against anyone who crosses him, such companies may be especially reluctant to anger the White House.
