U.S. President Donald Trump has fired two Democratic officials at the National Labor Relations Board, a major shakeup that will bring hundreds of cases accusing companies of unlawful labor practices to a standstill and paves the way for Republican control of the agency.

President Trump fired National Labor Relations Board General Counsel Jennifer Abruzzo. In an unprecedented move, he also ousted Democratic board member Gwynne Wilcox, leaving the board with no quorum.

The firing of National Labor Relations Board (NLRB) chair Gwynne Wilcox has effectively crippled the watchdog agency, with labor groups warning of widespread impacts for unions across the U.S.

President Donald Trump has removed a Democratic member of the U.S. National Labor Relations Board from office, an unprecedented move that will escalate an ongoing legal battle over the scope of the president's powers to control federal agencies.

Democrat Gwynne Wilcox, whose term was supposed to run through August 2028, said she believes her firing violates Supreme Court precedent.
