In the days following the violent clashes on Aug. 12 between rival groups of protesters in Charlottesville, Virginia, that resulted in the death of Heather Heyer, a 32-year-old legal assistant with the Miller Law Group, some corporate executives have openly criticized President Donald Trump for his immediate failure to condemn white supremacists.

CEOs from Under Armour Inc., Merck & Co. Inc., Intel Corp., the AFL-CIO and the nonprofit Alliance for American Manufacturing have all resigned from the Trump administration’s manufacturing council in the aftermath of last weekend’s unrest. Doug McMillon, CEO at Wal-Mart Stores Inc., chose to remain on the council but made headlines Tuesday for his harsh critique of Trump.
