MIAMI, Florida - In their first appearance as running mates, Hillary Clinton introduced her vice presidential pick, Virginia Senator Tim Kaine, at a Miami event Saturday.

Taking the stage before Kaine, Clinton first slammed this week's recently adjourned Republican National Convention, where she said she saw GOP nominee Donald Trump stoke "the fear and the anger and the resentment" of Americans.

Contrasting the Democrats' upcoming national convention, Clinton said, "next week in Philadelphia, we will offer a very different vision for our country -- one that is about building bridges, not walls, and embracing the diversity that makes our country great."

Introducing Kaine, she added that her vice presidential pick was "a man who doesn't just share those values, he lives them."

"Senator Tim Kaine is everything Donald Trump and Mike Pence are not," Clinton said. "He is qualified to step into this job and lead on day one. He is a progressive who likes to get things done."

Clinton ticked off a list of their commonalities -- growing up in the Midwest with fathers who ran small businesses -- before giving the podium up to Kaine.

"I'm feeling a lot of things today," Kaine said after Clinton's introduction. "Most of all gratitude. I'm grateful to you, Hillary, for the trust you've placed in me."

Kaine, who speaks fluent Spanish, said the two were "compañeros de alma in this great lucha ahead" -- "soul mates in this great fight ahead."
