According to a July 2021 book by "Washington Post" reporters Philip Rucker and Carol Leonnig, during the weeks following the election Chairman of the Joint Chiefs of Staff Mark Milley became concerned Trump was preparing to stage a coup, and held informal discussions with his deputies about possible ways to thwart it, telling associates, "They may try, but they're not going to fucking succeed. You can't do this without the military. You can't do this without the CIA and the FBI. We're the guys with the guns." The book also quoted Milley saying, "This is a Reichstag moment. The gospel of the Führer." Milley reportedly told police and military officials preparing to secure Joe Biden's presidential inauguration, "Everyone in this room, whether you’re a cop, whether you’re a soldier, we’re going to stop these guys to make sure we have a peaceful transfer of power. We’re going to put a ring of steel around this city and the Nazis aren’t getting in." The book also stated that a friend told Milley they were concerned that Trump's allies were attempting to "overturn the government".
