"Is it gonna be JD? Is it gonna be someone else? I don't know," Trump said while hosting a dinner for law enforcement leaders across the country in the Rose Garden on Monday evening.

The president then went on to conduct an impromptu poll, drawing laughter from the attendees.

"Who likes JD Vance?" and "Who likes Marco Rubio?", he asked as attendees cheered for their favourite choice.

"Sounds like a good ticket," Trump added, clarifying that neither candidate has his endorsement.

"That was a perfect ticket. By the way, I do believe that's a dream team, but these are minor details. That does not mean you have my endorsement under any circumstance."
