Outside the convention center, two delegates spoke with ABC News Digital about what they want to hear when J.D. Vance gives his first speech since being tapped as Trump's running mate.

"That's what we will want to hear tonight, that he has our values that he is going to, you know, that he's going to follow through on those values and when he is only the Vice President, but we're looking forward to four years from now," she said.

Another delegate from California said she was more familiar with Vance, having previously read his memoir "Hillbilly Elegy."

"He's young, he's smart and he knows what he's doing. He has a great compelling story, grew up in poverty, made it to the American dream. What could be more better than that?" she said.

Ohio Sen. J.D. Vance spoke at a fundraiser Wednesday afternoon where he gave a preview of what he will say during his speech at the Republican National Convention on Wednesday night.

"Now we're going to get out there and try to fire up the crowd tonight and make the case, a very easy case to make, but an important case to make that we have got to reelect President Donald J. Trump to the White House," Vance said.

Vance said that he will talk about the attempted assassination of Trump and how he has not wavered.

"He keeps on persevering. He keeps on fighting. President Trump has taken everything that they've thrown at him, and he's come out stronger, and the country has come out better for his service."
