An ex-member of the National Labor Relations Board (NLRB), whom President Trump fired last month, filed a lawsuit Wednesday challenging her dismissal and asking a federal court to reinstate her to the board.

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’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.
