A Texas billionaire is suing former failed presidential candidate and current gubernatorial challenger, Beto O’Rourke over claims he made following a deadly power outage.

Energy Transfer CEO Kelcy Warren filed the defamation suit in February over O’Rourke’s claim that energy companies made substantial profits during the 2021 winter storm and then made campaign donations to Texas Gov. Greg Abbott.

The Washington Examiner reports:

O’Rourke “intentionally, repeatedly, and widely disseminated his deliberate and defamatory falsehoods” in interviews, speeches, and on social media to “humiliate” Warren publicly, the suit said.

During the Feb. 2021 winter storm, the Texas power grid failed leaving millions without power and causing energy prices to spike.

As natural gas prices skyrocketed, Energy Transfer reportedly made billions, and Warren, a longtime Republican, donated $1 million to Abbott’s reelection campaign.

O’Rourke said he is being sued for “telling the truth and connecting the dots between the profits [Warren] made, the contributions he’s then made to Greg Abbott, and the policy that has been followed.”

“Greg Abbott and his top donors don’t want us talking about the fact that he took $4.6 million in campaign checks after allowing corporations to make billions in illegal profits while Texans froze to death in their homes,” O’Rourke tweeted earlier this week.
