President Trump launched an attack against Republican "Never Trumpers," calling them "human scum" in a scathing tweet.

"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," Trump tweeted. "Watch out for them, they are human scum!" 

Trump's attack appears to be aimed at his administration's special envoy to Ukraine, William Taylor, recently sat for closed-door testimony with those lawmakers the impeachment inquiry. Taylor offered up damaging evidence about the White House's efforts to pressure Ukraine for political purposes.

The president continued:

"Never Trumper Republican John Bellinger, represents Never Trumper Diplomat Bill Taylor (who I don't know), in testimony before Congress!" adding:

"It would be really great if the people within the Trump Administration, all well-meaning and good (I hope!), could stop hiring Never Trumpers, who are worse than the Do Nothing Democrats. Nothing good will ever come from them!"

This comes after he claimed that the Dems were interviewing individuals he'd never heard of as part of their impeachment inquiry, which is still ongoing.

"Don’t forget, many of these people were put there during Obama, during Clinton, during the Never Trump or Bush era," Trump said during a Cabinet meeting. "You know, you had a Never Trump or Bush. You have heard of those? Those people might be worse than the Democrats — the Never Trumpers. The good news is they're dying off fast."

During the meeting, he also implored the GOP to fight hard against the inquiry.
