One other mitigating factor may be that a single tweet from the president directed at a company can temporarily ding stock prices and inspire a magnifying storm of angry tweets from his followers, along with unwanted follow-up news coverage. Three more business leaders added their names Tuesday to the growing list of executives who have resigned from President Trump's manufacturing council: Scott Paul, the president of the Alliance for American Manufacturing; Richard Trumka, the president of the AFL-CIO; and Thea Lee, the AFL-CIO's deputy chief of staff. By departing, Paul, Trumka and Lee follow in the footsteps of three CEOs — Merck's Kenneth Frazier, Under Armour's Kevin Plank and Intel's Brian Krzanich — who resigned from the council on Monday following the president's heavily criticized handling of the deadly violence that erupted at a white supremacist rally in Charlottesville, Va., over the weekend. He stepped down from President Trump’s manufacturing council, saying “America’s leaders must honor our fundamental values by clearly rejecting expressions of hatred, bigotry and group supremacy.”

–8:54 a.m.: Trump tweets that Frazier will now “have more time to LOWER RIPOFF DRUG PRICES!”

–1 p.m.: The president delivers a speech in which he calls the KKK, neo-Nazis and white supremacists ‘repugnant.’

–11:37 a.m.: Scott Paul, president of Alliance for American Manufacturing, resigns. Even before Paul posted about his resignation on Twitter, the president beat him to the tweet, writing some 15 minutes earlier, "For every CEO that drops out of the Manufacturing Council, I have many to take their place. The president followed up later in the day, tweeting that Merck "is a leader in higher & higher drug prices while at the same time taking jobs out of the U.S. Bring jobs back & LOWER PRICES!"
Alliance for American Manufacturing president Scott Paul, AFL–CIO president Richard Trumka and the union's former chief of staff Thea Lee resign from President Trump's American Manufacturing Council due to their disagreements with Trump's response to the rally. The three corporate executives join Merck CEO Kenneth Frazier, Intel CEO Brian Krzanich and Under Armour CEO Kevin Plank, who also resigned from the council in protest the day prior.
