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 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.
