US Defence Secretary Pete Hegseth says an attempt to impeach him by a Republican politician is a “farce” aimed at damaging President Donald Trump. “What one disgruntled and defeated congressman is attempting is not oversight, and it's not accountability. It's a political spectacle, a personal manifesto driven by ego and resentment,” Mr Hegseth said of Representative Thomas Massie's impeachment push. “It's a farce and it's a stunt, and everybody knows it.”
