Don Lemon warns Trump will 'retrofit' laws to prosecute him after judge rejects charges

Lemon followed and spoke to demonstrators who disrupted a church service in a video he posted to his YouTube channel.

"I'm not naive. I think they're probably going to try again and again as they did with Tish James and Comey and everyone. If one doesn't work, then they try something else and that fails, and they try something else, and then they just don't give up, because they, you know, they want to save face, but I don't know what's next," Lemon told his former colleague in the Scripps News interview.

Lemon said that he needed to be in it for the long haul, as well as "keep calm and carry on."

"It's notable that I've been cast as the face of a protest I was covering as a journalist - especially since I wasn't the only reporter there. That framing is telling," Lemon told Fox News Digital in a statement earlier this month. "What's even more telling is the barrage of violent threats, along with homophobic and racist slurs, directed at me online by MAGA supporters and amplified by parts of the right-wing press."
