Five former defense secretaries, including James Mattis and Leon Panetta, have issued a scathing letter condemning President Donald Trump's recent firings of top military officials. The letter, published on Thursday, called for immediate congressional hearings to investigate the dismissals of Joint Chiefs Chairman Gen. CQ Brown and other senior officers.
The defense secretaries accused Trump of undermining national security and attempting to politicize the U.S. military by dismissing key leaders. They urged senators to block any new Department of Defense nominations in response to the firings.
