A new ad by Sen. John Cornyn’s (R-TX) reelection campaign will hit his runoff primary opponent, Texas Attorney General Ken Paxton, over his ties to far-right commentator Tucker Carlson, pointing to Carlson’s criticisms of President Donald Trump, while also honing in on his attacks against Trump’s support for Israel and the war in Iran.

The minute-long ad — a five-figure buy set to begin airing on digital platforms on Friday, Jewish Insider has learned — appears to be one of the first mentions of Carlson as a target in GOP primary campaigns.

The ad opens by highlighting Trump’s support for Israel and efforts to counter Iran, contrasting that with Carlson, whom the ad states is “attacking our president for keeping America and Israel safe,” including a clip of Carlson describing the Iran war as “vile, on every level.”

It highlights that Trump had attacked Carlson as a “low IQ person” and a “fool” before playing a clip of Paxton appearing on Carlson’s show, in which Carlson expresses his support for the attorney general. “Ken Paxton still accepts Tucker Carlson’s endorsement,” the ad intones.

“Ken Paxton is taking Carlson’s side over President Trump,” the ad claims. “President Trump and MAGA stand with Israel. Ken Paxton and Tucker Carlson stand for nothing.”

Paxton has, in fact, been strongly supportive of the war in Iran and of Israel and has not expressed similar views to Carlson on the subject.

The ad closes with what appears to be an AI-generated selfie depicting Carlson and Paxton, next to a running money counting machine — a reference to corruption scandals involving Paxton, which Cornyn has highlighted on the campaign trail.

“It’s time for the crook to renounce the fool,” the ad’s narrator states.

Recent public polling has found Paxton with a narrow lead over Cornyn in the runoff, even though he trailed Cornyn in the three-person GOP primary last month. While Trump was, at one point, expected to endorse a candidate for the runoff race to clear the field, he has not yet done so.
