(NewsNation) — The 2024 presidential election is headed toward a 2020 rematch between President Joe Biden and former President Donald Trump, but Robert F. Kennedy Jr. is not going to bow out without a fight.

Now, he says Trump’s team reached out to him about possibly serving as his vice president, but RFK Jr. says he would not accept the position if offered today.

“I would not take that job. And I’m flattered that President Trump would offer it to me, but it’s not something that I’m interested in,” RFK Jr. told NewsNation.

However, Trump’s senior adviser Chris LaCivita said the team never approached RFK Jr. “NO ONE from the Trump Campaign ever approached RFK jr (or ever will),” LaCivita posted on X.

Recent polls have the Independent candidate around 18% as he pushes for ballot access in all 50 states.

Kennedy addressed a packed crowd at his rally in Charleston, West Virginia, Saturday. Speaking to NewsNation’s Rich McHugh about his campaign beforehand, he addressed his views on the crisis at the southern border.

“I believe that under the Constitution, Texas has the right to defend its border. Under Article Four of the Constitution, the U.S. has the obligation to defend states against invasions by a foreign country. As president of the United States I would be defending it, Texas wouldn’t have to do it,” RFK Jr. said.

RFK Jr. previously opposed Trump’s plans to build a wall on the U.S.-Mexico border, but now says his views have changed.

“When I went down and saw the border, my mind completely shifted about what’s happening down there. And we don’t need a border wall from 2,200 miles from Brownsville, Texas, to San Diego. You definitely need a physical barrier in certain parts of the border,” he added.

Previously running as a Democrat against Biden, Kennedy is now on the ballot in New Hampshire and Utah as an independent. In an interview on Saturday, he signaled that he would be open to running as a Libertarian candidate.
