President Trump lashed out at Sen. Mitt Romney as a “pompous ‘ass’ who has been fighting me from the beginning” after the Utah Republican called Trump’s discussions with foreign leaders “brazen and unprecedented.”

“Somebody please wake up Mitt Romney,” Trump tweeted Saturday, defending his conversations as “congenial and very appropriate.”

“Mitt Romney never knew how to win,” Trump continued. “He is so bad for R’s!”

Romney lost his race against President Barack Obama in 2012, but as a member of the Senate would be in position to vote on Trump’s removal if the House impeaches the president.

But Trump tweeted that it’s Romney who should be bounced from his office.

“I’m hearing that the Great People of Utah are considering their vote for their Pompous Senator, Mitt Romney, to be a big mistake,” he wrote — adding the hashtag #IMPEACHMITTROMNEY.

Meanwhile, Rep. Alexandria Ocasio-Cortez escalated her Twitter war against Trump, calling him an anti-Semite for criticizing Rep. Adam Schiff.

“Understand that Trump is engaged in deliberate, atrocious, targeted anti-Semitism,” the freshman Democrat posted Saturday with a retweet of a Friday opinion piece that likened Trump’s rhetoric to neo-Nazi tactics.

Trump derided Schiff, who is heading the House Intelligence Committee’s impeachment effort, as a “Do Nothing Democrat Savage” in a Sept. 28 tweet.
