Merck CEO Kenneth Frazier was the first to quit yesterday.
He made his name as the company's top lawyer, steering it through daunting litigation over Vioxx, its widely used painkiller that was withdrawn in 2004 after being linked to heart attacks.

Trump had appointed Liveris to lead the manufacturing council, which was meant to serve as is the principal private sector advisory committee to the secretary of commerce on the manufacturing in the United States.
Frazier's decision was followed hours later by other CEOs on the council, including Intel and Under Armour.
