Robert F. Kennedy Jr. is calling on former President Trump to formally debate him during the upcoming Libertarian Party convention.

Kennedy, an independent who considered joining the Libertarian Party after a failed primary bid as a Democrat, wants to take on Trump during the forum held later this month in Washington.

“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 wrote in part in a lengthy post on X on Tuesday. “It’s perfect neutral territory for you and me to have a debate where you can defend your record for your wavering supporters.”

“You yourself have said you’re not afraid to debate me as long as my poll numbers are decent,” Kennedy wrote. “Well, they are. In fact, I’m the only presidential candidate in history who has polled ahead of both major party candidates in head-to-head races.”

Kennedy pointed to data from Zogby, a polling and analytics firm, indicating that the environmental lawyer wins the election over Trump in a two-candidate race, without factoring President Biden into the hypothetical matchup.
