Vance says his mission at GOP convention speech is 'to fire up the crowd tonight'

MILWAUKEE – GOP vice presidential nominee Sen. JD Vance says his mission as he delivers his acceptance speech on day three of the Republican National Convention is simple.

Vance, the 39-year-old senator from Ohio whom former President Trump named as his running mate at the beginning of the week, on Wednesday night will address the roughly 2,400 delegates and thousands of other attendees packed inside Milwaukee's Fiserv Arena, and the millions of Americans watching the GOP convention from home.

"We're gonna get out there and try to fire up the crowd tonight," Vance said at a financial event hours before his prime time address at the convention.

The senator added that he would "make the case, a very easy case to make, but an important case to make, that we have got to re-elect President Donald J. Trump to the White House."

And he joked, "I'm very excited about this evening, and I don't plan to screw it up. But if I do, it's too late. He [Trump] made the pick, right. It's official now."

Trump, in making his greatly anticipated and high-stakes running mate announcement as the GOP convention kicked off in swing-state Wisconsin's largest city, will now share the ticket with one of his top supporters in the Senate, a one-time Trump critic who has transformed into a leading America First ally.

The former president and Vance teamed up on Monday and Tuesday nights in the Trump family box above the floor of the GOP convention.

Vance, a former venture capitalist and the author of the bestselling memoir "Hillbilly Elegy" before running for elective office, on Wednesday night will appear on the podium to tell his story.
