California Gov. Gavin Newsom tore into Florida Gov. Ron Desantis on Saturday, calling him a “bully,” and said he is more worried about Fox News host Tucker Carlson than former President Donald Trump.

The comments in deep-red Texas mark an escalating feud between the two governors, both of whom are seen as 2024 presidential contenders if they choose to run, and take aim at the most-watched cable news host in the United States.

“I worry about Trump. I worry about Trumpism,” Newsom said at the Texas Tribune Festival in Austin. “I worry more about Tucker Carlson. I worry about Ron Desantis.”

“He’s a bully,” Newsom said of Desantis. “He threatened the Special Olympics with $27 million in fines. Who does that?”

Desantis made the threat after the 2022 Special Olympics attempted to enact a vaccine mandate for its games in Florida. The organization eventually withdrew the requirement.

“Abbott is light years ahead in policy than Desantis, but Desantis has weaponized it to the next level,” Newsom added, referring to Texas Gov. Greg Abbott.

The California governor would go on to comment on how “remarkable” it was that Trump made democracy “partisan” but added that voters’ focus should be on local and state elections.

Both Newsom and Desantis are up for reelection in 2022 after Newsom survived a recall election in 2021. Meanwhile, Desantis has broken national fundraising records.

Neither governor has declared their candidacy for president, but both have been making national headlines as their clashes heat up. Newsom sent a letter to the Department of Justice seeking an investigation into the flight of migrants to Martha’s Vineyard in Massachusetts. Desantis dismissed the letter, joking that Newsom’s “hair gel was interfering with his brain function.” Newsom would go on to challenge Desantis to a debate on Twitter.

Carlson has also been talked about as a possible presidential contender, but he has said he does not plan to run in 2024.

Other speakers at this year’s Texas Tribune Festival included Rep. Liz Cheney (R-WY), former Secretary of State Hilary Clinton, and Transportation Secretary Pete Buttigieg.
