Vivek Ramaswamy, Trump's former GOP primary rival, received a warm welcome, with people rising to their feet for a long ovation.

He launched into a fiery speech that included leading the crowd in a call-and-response of "vote Trump" that grew louder with each prompt.

"If you want to seal the border, vote Trump," he said. "If you want to restore law and order in this country, vote Trump. If you want to reignite the economy in this country, vote Trump. If you want to revive national pride in this country, vote Trump. If you want to make America great again, vote Trump."

Ramaswamy said the "most important reason" to vote for Trump is that he "will actually unite this country. Not through empty words but through action."

Ramaswamy, who was notably a millennial candidate, also had a message for young voters.

"You will be the generation that saves this country," he said. "You want to be a rebel? You want to be a hippie? You want to stick it to the man? Show up on your college campus and try calling yourself a conservative. Say you want to get married, have kids -- teach them to believe in God and pledge allegiance to their country, because you know what? Fear has been infectious in this country, but courage can be contagious, too."
