Rep. Marsha Blackburn (R-Tenn.) fired back Wednesday after one of her Democratic colleagues joked about her jumping off a bridge.

Rep. Steve Cohen (D-Tenn.) made the controversial remark last week during a prayer breakfast at a Memphis church hosted by Blackburn's Senate race opponent, former Gov. Phil Bredesen.

“The big orange president, he’s going to come down here and he is going to endorse Marsha Blackburn, because Marsha Blackburn, if he says, ‘Jump off the Harahan Bridge,’ she’ll jump off the Harahan Bridge,” Cohen said in the audio obtained by The Huffington Post.

“I wish he’d say that," Cohen continued, eliciting laughter from the audience.

The congressman later told The Huffington Post that it was "obviously humor" and he wishes Blackburn no physical harm, but he also wishes she wasn't a "lackey" for Trump.

On "Fox & Friends," Blackburn -- who's running against Bredesen to replace retiring GOP Sen. Bob Corker -- said Bredesen should have spoken up against the remark.

"I would expect that with my opponent, Phil Bredesen, being in the audience that he would have said, 'We don't say things like that. We don't wish someone's demise or death,'" Blackburn said.

Cohen made headlines at a House hearing in July for praising former FBI agent Peter Strzok and saying he deserved a Purple Heart for putting up with attacks from Republican lawmakers.

"People talk a lot about civility in the political process," Blackburn said. "And as you said, Congressman Cohen had had other comments that Tennesseans did not view favorably."

She added that she and her fellow Republican lawmakers often have to deal with personal threats.

"I do not know why there is such a level of vitriol," Blackburn said. "What we need to realize is our nation and the cause of freedom [have] been well-served by a robust, respectful two-party debate. And that is what the people of Tennessee want to see."
