Under Armour CEO Kevin Plank on Monday announced he was stepping down from President Donald Trump's American Manufacturing Council, because "Under Armour engages in innovation and sports, not politics."
Merck & Co. CEO Kenneth Frazier also resigned on Monday, citing Trump's response to the violence in Charlottesville, Va., on Saturday when white nationalists clashed with counter protestors.
"Our country's strength stems from its diversity and the contributions made by men and women of different faiths, races, sexual orientations and political beliefs," Frazier said in a statement.
"America's leaders must honor our fundamental values by clearly rejecting expressions of hatred, bigotry and group supremacy, which run counter to the American ideal that all people are created equal," he continued.
"As CEO of Merck, and as a matter of personal conscience, I feel a responsibility to take a stand against intolerance and extremism."
