President Donald Trump fired the National Labor Relations Board’s general counsel and one of its Democratic board members late Monday, setting up a likely legal battle over presidential power.

Both Jennifer Abruzzo, the general counsel, and Gwynne Wilcox, the board member, were Democrats who took a broad view of workers rights under collective-bargaining law. Wilcox’s term as a board member was set to run through August 2028.

She said in a statement through a spokesperson that she believes her firing, which was first reported by Bloomberg, violates “long-standing Supreme Court precedent.”

“I will be pursuing all legal avenues to challenge my removal,” Wilcox said.
