RFK Jr. challenges Trump to a debate at Libertarian convention

• Kennedy has also reportedly met the signature threshold to appear on the ballots in at least six more states.

What they're saying: Kennedy, who has adopted a more Trumpian tone, said in a letter to Trump posted on X that he deserves the debate because of his polling numbers and because he's "drawing a lot of voters from your former supporters."

• "They are upset that you blew up the deficit, shut down their businesses during Covid, and filled your administration with swamp creatures," Kennedy said. "So I'd like to make you an offer."
• "We're both going to be speaking at the upcoming Libertarian convention on May 24 and 25," Kennedy added. "It's perfect neutral territory for you and me to have a debate where you can defend your record for your wavering supporters."

Trump, who at one point said Kennedy's campaign was "great for MAGA," claimed last month Kennedy was a "Democrat plant" and a "wasted protest vote."

• After that outburst, Kennedy asked Trump for a debate.

The big picture: While Trump has been open to debating Biden, he's avoided debates with other candidates, such as those who challenged him for the GOP primary.

• Conservative media has shifted the volume and tone of coverage on Kennedy in recent weeks after he switched to running as an Independent instead of a Democrat, Axios' Alex Thompson and Sara Fischer report.
