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.

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’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.
