Concern about a possible coup attempt or military action
In December 2020, Newsweek reported the Pentagon was on red alert, and ranking officers had discussed what they would do if Trump decided to declare martial law. The Pentagon responded with quotes from defense leaders that the military has no role to play in the outcome of elections.[645]
When Trump moved supporters into positions of power at the Pentagon after the November 2020 election, Chairman of the Joint Chiefs of Staff Mark Milley and CIA director Gina Haspel became concerned about the threat of a possible coup attempt or military action against China or Iran.[646][647] Milley insisted that he should be consulted about any military orders from Trump, including the use of nuclear weapons, and he instructed Haspel and NSA director Paul Nakasone to monitor developments closely.
