Tonight on "Hannity," Sean spoke to RNC Chairman Reince Priebus to break down what it will take for a Republican presidential candidate to win the nomination, plus what would happen in the event of a contested convention.

Priebus said that if someone gets the majority (1,237) of delegates before the convention, they're going to be the nominee.

"There's no doubt about that," he said. The only question then, is what happens if a candidate doesn't reach the majority before the national convention in Cleveland.

Priebus said that in the event of a contested convention, it's "really important for the party to play it straight, to not play games, to be transparent."
