Why it matters: A senior administration official says a wave of firings at the Pentagon and the hiring of Ret. Army Col. Douglas Macgregor is in part a settling of Trump’s personal scores — but senior White House officials also have made clear “they want them more publicly to talk about getting out of Afghanistan by the end of the year.”

Trump, who ran in 2016 on a promise to bring U.S. troops home, is frustrated with the slow pace of withdrawing troops from the Middle East, another senior administration official said.

The president has told advisers on numerous occasions he wants troops home from Afghanistan by Christmas.

In a 2019 interview with Fox’s Tucker Carlson, Macgregor said he would advise the president to get out of Afghanistan “as soon as possible,” including removing the U.S. embassy from Kabul, and that talking to the Taliban was unnecessary.
