Senator Lindsey Graham (R-SC) spoke out over the weekend to declare Lara Trump to be the “biggest winner” of impeachment trial as he threw his support behind her for Senate in North Carolina. Republican Senate candidate Mark Walker of North Carolina, however, is already pushing back against Graham on this.

While appearing on Fox News on Sunday, Graham said that the decision of retiring GOP Sen. Richard Burr of North Carolina to vote in favor of convicting former President Donald Trump in his impeachment trial makes Lara a shoe-in to win the 2022 Republican nomination to succeed Burr.

“The biggest winner of this whole impeachment trial I think is Lara Trump,” Graham said. “My dear friend Richard Burr, who I like and I’ve been friends to a long time, just made Lara Trump almost the certain nominee for the Senate seat in North Carolina to replace him if she runs, and I certainly would be behind her because I think she represents the future of the Republican Party.”

Walker, the only major Republican to officially jump into this race so far, fired back on Monday morning in an interview with Fox Business.

“In the words of I believe it was John Ashcroft, Lindsey is always confident but not always right,” he said. He went on to claim that he is not paying attention to other potentially candidates who may jump into this race, which is likely to be hotly contested.

“We can’t control what anyone else is doing,” Walker said. “This is something we’re focused on because it’s in our heart to do, service has been part of our life for nearly a quarter century and we’re going to continue to do so.”

Doug Heye, a former Republican National Committee spokesman and a North Carolina native who previously worked for Burr, also took issue with what Graham said.

“I don’t see how Saturday’s vote affect that at all,” Heye said. “You’ve got to do some crazy kind of algebra and cheating your math to get that.”

He added that Lara “could raise a ton of money” if she ran, but he questioned if she’ll actually launch a campaign.
