President Trump on Wednesday ripped the coalition of Republicans who oppose his presidency as “human scum!”

“The Never Trumper Republicans, though on respirators with not many left, are in certain ways worse and more dangerous for our Country than the Do Nothing Democrats. Watch out for them, they are human scum!,” Trump wrote on Twitter.

The president didn’t single out any particular “Never Trumper” from the GOP lawmakers and pundits who speak out against him and his administration, but he called out Utah Sen. Mitt Romney during a cabinet meeting at the White House on Monday.

“The two things they have: They’re vicious and they stick together,” the president said about Democrats. “They don’t have Mitt Romney in their midst. They don’t have people like that.”

During the meeting, he urged his Republican colleagues to unite and defend him in the impeachment probe underway in the Democrat-controlled House.

“And Republicans have to get tougher and fight,” Trump said. “We have some that are great fighters, but they have to get tougher and fight because the Democrats are trying to hurt the Republican Party for the election, which is coming up, where we’re doing very well.”

Romney, the 2012 GOP presidential nominee, opposed Trump in 2016, but he has denied leading the “Never Trump” movement since he was elected.

But he has still been outspoken about Trump’s presidency.

Romney condemned Trump’s pulling US troops out of Syria as abandoning America’s Kurdish allies and saying it would be remembered as “a bloodstain on the annals of American history.”

It was revealed Monday that Romney used a private Twitter account and the handle Pierre Delecto to lurk online and criticize the president.

Former Sen. Jeff Flake, a noted “Never Trumper,” announced he would not run for re-election in 2018 and rebuked his GOP colleagues for the “alarming and dangerous state of affairs” under Trump.

He recently estimated that as many as 35 Republican senators would opt to impeach Trump if they could cast their vote in private.
