The caucus means Paul would not be on the ballot twice in the same election, which is barred by Kentucky law.
McConnell was initially skeptical about the idea, but changed his mind after Paul told him it would be a one-time event and he would raise money to pay for it, according to a statement from McConnell's Chief of Staff Brian McGuire first reported by the Lexington Herald-Leader.
The move only affects the primary election. Paul would likely need a court order for the general election should he win the Republican presidential nomination.
