"Late Show" host Stephen Colbert sounded off on Twitter over calls for fellow late-night host Jimmy Kimmel to quit addressing politics on his show, joking that politics is best left to reality TV stars like President Trump.

"Please @JimmyKimmel - stay out of politics. Leave the important stuff to reality TV stars with a knack for bankrupting casinos," Colbert tweeted.

Kimmel has drawn the ire of Republican lawmakers this week over his vocal opposition to the new ObamaCare repeal bill put forth by Sens.

Earlier this week Kimmel ripped Cassidy for failing “the Jimmy Kimmel test,” a phrase Cassidy created himself during previous efforts to repeal ObamaCare.

“Your child with the pre-existing condition will get the care he needs if — and only if — his father is Jimmy Kimmel. Otherwise, you might be screwed,” Kimmel said, drawing laughs from the audience Tuesday.

“Not only did Bill Cassidy fail the Jimmy Kimmel test, he failed the Bill Cassidy test. He failed his own test,” Kimmel added.

Republicans have gone after Kimmel for his criticism, suggesting he isn't qualified to talk about it as a comedian, prompting Colbert's response.

Cassidy, for his part, says he would "love" to return to Kimmel's show and discuss his health care proposal.

"Jimmy doesn't understand, and not because he's a talk show host, because we've never spoken," Cassidy said on Thursday. "He's only heard from those on the left, who are doing their best to preserve ObamaCare. He's not heard from me — we've not spoken — and I would love to talk to him about this."
