Clinton's vice presidential pick is making his official debut today among an energetic crowd of more than 4,000 people packed into FIU's Panther Arena.
"Please join me in welcoming the next vice president my friend senator, Tim Kaine," said Hillary Clinton at Saturday's rally.
Saturday's rally in Miami marks their first public appearance together. So who is Tim Kaine?

Today the current Virginia senator introduced himself to America on a larger stage.
"I'm one of only 20 people in American history to serve as a mayor, a governor and a united states senator," said Kaine.
The senator also fought housing discrimination as a civil rights lawyer in Richmond and he speaks fluent Spanish.
Kaine greeted his Spanish speaking audience by saying, "Bienvenidos a todos."
Taking time off from Harvard to work with missionaries in Honduras. Rally goers reacted to this vice president selection after his speech.
"I did not know who he was honestly but I really loved the way he talked. He talked about himself," said Yaneli Gonzalez, an attendee at the rally.
Andrea Gutierrez also attended the rally and said Clinton couldn't have picked anybody better. "I feel like she got to know him and she wants us to get to know him," said Gutirrez.
While some ralliers were convinced, there are critics calling him the safe choice. The new team discussed also discussed gun control, building an economy for all and immigration.

"Do you want a you're fired president or a you're hired president?" asked Kaine.
