The "Last Word" host on Monday delivered what Sen. Mark Kelly (D-Ariz.) called "a great summary" of his new lawsuit against the secretary of defense.

Hegseth said the Pentagon would cut Kelly's military retirement pay over his participation in a video telling U.S. troops they can refuse unlawful orders.

Defense Secretary Pete Hegseth wants to reduce the senator's pay and rank in an act of retaliation, a new lawsuit alleges.
