AFL-CIO President Richard Trumka quit President Trump’s manufacturing council “effective immediately” Tuesday evening, soon after the president blamed “both sides” for the weekend violence in Charlottesville, Va. The leader of the nation’s largest labor federation condemned Trump’s response, saying he was condoning racial bigotry.

“We cannot sit on a council for a president who tolerates bigotry and domestic terrorism. President Trump’s remarks today repudiate his forced remarks yesterday about the KKK and neo-Nazis. We must resign on behalf of America’s working people, who reject all notions of legitimacy of these bigoted groups,” Trumka tweeted. Thea Lee, formerly the AFL-CIO’s deputy chief of staff and now an economist working with the organization, also resigned from the council, the labor federation said.
