Watch Live: RNC Day 2 underway with DeSantis and Haley set to speak

The second night of the Republican National Convention is underway in Milwaukee, where former President Donald Trump's onetime rivals for the party's nomination are set to speak in support of his candidacy as the party tries to project a united front heading into November.

Gov. Ron DeSantis, former U.N. Ambassador Nikki Haley and Vivek Ramaswamy are all scheduled to address delegates on Tuesday evening. Sen. Marco Rubio, who Trump passed over for his vice presidential running mate, is also among the list of speakers.

The theme for the second day of the convention is "Make America Safe Once Again," a variation of Trump's "Make America Great Again" tagline.
