The president of the largest federation of unions in the United States is not ruling out the possibility that ALF-CIO, which represents over 12 million active and retired workers across the country, could endorse President Donald Trump for re-election in 2020.

Speaking at a breakfast roundtable sponsored by The Christian Science Monitor on Wednesday, Richard Trumka was asked by Newsmax‘s John Gizzi if it was “outside the question” the AFL-CIO might endorse Trump for re-election given the popularity the president enjoys amongst a cross-section of the union’s membership.

“You have many members who like President Trump and voted for him in 2016, is that still the case?” Gizzi asked. “Is there a large cadre of Trump loyalists, who are also card-carrying members of the AFL-CIO and is it outside the question, outside reality that you might endorse him for re-election next time?”
