Gwynne Wilcox, who is suing President Trump for ousting her from the National Labor Relations Board, said she was "stunned" when she received a letter from the White House late on Jan. 27 firing her.

Gwynne Wilcox, the former chair of the nation's top labor watchdog, the National Labor Relations Board, was fired by President Trump last week. It's the first time a board member has been removed from the agency in its nearly 90-year history.

Gwynne Wilcox’s lawsuit is the first to challenge the president’s ouster of several members of independent boards — moves that appear to contravene a 1935 Supreme Court ruling.
