Two top labor leaders have stepped down from President Donald Trump's manufacturing council, joining a string of business leaders who have done so following the president's response to an attack at a white nationalist rally over the weekend.

AFL-CIO President Richard Trumka and deputy chief of staff Thea Lee said Tuesday they resigned from the council. They join Merck CEO Kenneth Frazier, Under Armour CEO Kevin Plank, Intel CEO Brian Krzanich and Scott Paul of the Alliance for American Manufacturing also stepped down in the past two days.

Their moves came after Trump's tepid response to the car attack, which killed one person and wounded 19 others. On Tuesday, Trump again blamed both the white supremacists and the counterprotesters for the violence, reigniting bipartisan criticism only a day after he condemned white supremacists and hate groups.

In a statement on behalf of himself and Lee, Trumka said "we must resign on behalf of America's working people, who reject all notions of legitimacy of these bigoted groups."
