President Trump called for Sen. Mitt Romney (R-Utah) to be impeached Saturday and argued that Republican voters in the state made a "mistake" nominating Romney for the Senate.

In a pair of tweets, the president argued that the Utah Republican should be removed from office and that former Sen. Jeff Flake (R-Ariz.), another frequent Trump critic, was "better" than Romney.

"I'm hearing that the Great People of Utah are considering their vote for their Pompous Senator, Mitt Romney, to be a big mistake. I agree! He is a fool who is playing right into the hands of the Do Nothing Democrats! #IMPEACHMITTROMNEY," Trump tweeted.

"No Kevin, Jeff Flake is better!" he added, responding to Fox News reporter Kevin Corke's tweet questioning whether Romney was "the new #JeffFlake."

Senators cannot be impeached but can face recall votes in some states. Utah does not have any provisions in state law for recalling a sitting senator.

Romney, who was elected to the Senate last year, faced the highest disapproval rating of Utah's congressional delegation, according to a poll taken in July.

His office did not immediately return a request for comment from The Hill.
