It's unclear how now former Homeland Security Secretary Kristi Noem discovered she was fired, and reports Thursday indicate she could have found out about it on Truth Social.

CNN senior White House correspondent Kristen Holmes reported that Noem was speaking at the Sergeant Benevolent Association Major Cities Conference in Nashville just as President Donald Trump had announced via his Truth Social platform that he would replace her with MAGA ally and former MMA fighter Sen. Markwayne Mullin (R-OK) and demote her to "Special Envoy for the Shield of the Americas." A White House official said she was apparently aware as she was speaking that she had lost her position.

"Now I do not know the order of events in terms of whether or not she learned before or he actually posted this, or during the time that he was posting this, that I'm still trying to get to the bottom of," Holmes said. "But she is aware that he has put this out there now, the other thing to note here is that she's been asked a number of questions, and nobody has asked her about it, so clearly there's probably several people in that audience who don't know that this announcement just happened roughly an hour ago or less."
