Tucker Carlson threatened to host Gov. Greg Abbott's primary opponents because he won't come on the show

• Fox News host Tucker Carlson threatened to invite Gov. Greg Abbott's primary opponents because the governor won't come on his show.
• Carlson railed against the governor about the migrant "invasion" at the Texas border.
• Abbott appeared on Fox News host Sean Hannity's show directly after Carlson's ended Tuesday night.

Fox News host Tucker Carlson threatened to host Texas Gov. Greg Abbott's primary opponents on television after the politician repeatedly refused to go on Carlson's show.

Carlson said he's invited the governor onto his show, "Tucker Carlson Tonight," on several occasions to speak about the rising migrant numbers at the Texas border where thousands of Haitian immigrants are seeking refuge from an earthquake and presidential assassination in their country.

"We've asked Texas Gov. Greg Abbott many times to come on this show to explain why he hasn't called the National Guard to seal the Texas border to protect the rest of us from this invasion," Carlson said. "Greg Abbott has refused to come on repeatedly."

Abbott is no stranger to Fox News: He frequently appears on the channel and appeared on host Sean Hannity's show directly after Carlson's segment ended.

Appearing on other Fox News shows is not enough for Carlson, so he issued a warning to the governor:

"We plan to invite his primary opponents onto this show to describe what they would do if they ran Texas," Carlson said. "We'd like to give Gov. Greg Abbott one more chance. Sincerely, tell us how you plan to save the rest of us from what's happening in your state."

Abbott handily defeated his two primary election opponents in his 2018 gubernatorial run, winning 90.4 percent of the vote. He later won in the general election by 15 percentage points.

Abbott's approval ratings, however, are tanking in the state - only 41% of Texans approve of his job according to the Texas Politics Project at the University of Texas at Austin - leaving an opening for Republican and Democratic challengers alike.

But even still, no Democratic candidate has declared their intention to run for governor. Former US Rep. Beto O'Rourke is reportedly "making and receiving calls" about a possible run but has yet to make an official announcement.
