Expert flags 'bigger risk' Trump just created by firing Kristi Noem

A former GOP speechwriter flagged a "bigger risk" that President Donald Trump just created after he fired Department of Homeland Security Secretary Kristi Noem.

On Thursday morning, Trump posted on Truth Social that he was replacing Noem with Sen. Markwayne Mullin (R-OK), effective on March 31. Noem was given another position, Special Envoy for The Shield of the Americas, for an initiative that Trump said he will announce more details on later.

The decision happened at a time when the Trump administration had launched direct strikes against Iran, an operation that killed Ayatollah Ali Khamenei and several of the country's top military and political leaders. Trump has said there is a chance that Iran may strike the U.S. in retaliation for the strikes.

David Frum, a former speechwriter for George W. Bush and a staff writer at The Atlantic, told CNN's Kaitlan Collins on Thursday night that the decision to remove Noem was alarming.

"The United States is now engaged in a big global war against the world's leading state sponsor of terrorism," Frum said. "There is, of course, a real risk that a state sponsor of terrorism could commit terrorism inside the United States, and an even bigger risk that the administration could claim that their acts of terrorism are coming."

"It has never been more vital to have professional, responsible, competent honest, trustworthy leadership of the Department of Homeland Security that is committed to respecting the freedom of americans and not in any way allowing that department to be used to tamper with the 2020 elections but that's notthe leadership it's had, and that's not the leadership that the president would like it to have," he continued.
