NBC’s Tom Costello worried Tuesday that Daily Caller co-founder and former Fox News host Tucker Carlson will not be policed for his speech on his new show.

Carlson announced Tuesday that his show will air exclusively on Twitter going forward.

“As of tonight, there aren’t many platforms left that allow free speech,” Carlson said in his announcement video. “The last big one remaining in the world, the only one, is Twitter, where we are now. Twitter has long served as the place where our national conversation incubates and develops. Twitter is not a partisan site – everybody’s allowed here, and we think that’s a good thing.”

Carlson said his show will air “soon.”

Costello grew animated over the news during Tuesday night’s segment of “Hallie Jackson NOW.”

“Okay, well listen, Twitter was already under fire for misinformation, disinformation, all-out lies, anti-Semitism [and] racism before Elon Musk took over, and now it’s gotten kind of crazy — seemingly unmoored, if you will. Will anybody be able to police what Carlson says, or is this the point? It’s just a free for all?” he wondered.

“I think this is the point, it is a free for all, it’s what Elon Musk wants to provide,” former CNN host Brian Stelter said, arguing Carlson’s announcement “may cement” Twitter as a “right-wing website.” (RELATED: ‘That’s What He Should Do’: Megyn Kelly Gives Tucker Direct Advice About How To Handle Fox)

Stelter then argued Carlson was a “drag” on Fox’s profits, with both him and Costello claiming advertisers will leave Twitter over the launch of Carlson’s new show.
