He'll finish his day with a rally in Nevada, which hosts it's presidential caucuses on Tuesday.

The Vegas caucus is on Tuesday, and Rubio told supporters "When it comes to our campaign, what happens in Vegas is not staying in Vegas."

But Rubio won't be in Nevada when the winner is announced on Tuesday.

He's scheduled to campaign in the state Sunday night through Tuesday morning before heading to Minnesota and Michigan.
