 It's a tradition at political conventions for candidates who were attacking one another just months ago to demonstrate that they're now on board. To that end, former ambassador Nikki Haley is scheduled to speak tonight. She was among Trump's toughest critics during the campaign and the last to drop out of the race. She's expected to voice full support for Trump. Then Governor Ron DeSantis of Florida will take the stage. He had early high expectations during the primaries.
