RICHMOND, Va. (WVIR) - A man who has known U.S. Senator Tim Kaine (D) for more than three decades is weighing in on his vice presidential nomination.

U.S. Senator Mark Warner (D) says from the time he met Kaine in law school through now, he's always been a decent and trustworthy person.

Warner also believes Kaine will be, what he calls, a steadying figure for the Hillary Clinton campaign.

Kaine’s political career began by serving in Richmond city politics. Warner later worked with him when he was governor and Kaine was the lieutenant governor.

Now that they’re both serving in the U.S. Senate, Warner says he can count on Kaine for support.

While Warner concedes many Republicans in the General Assembly disagree with Kaine's politics, he thinks they admire him for who he is.

“They say, 'well we might not agree with his policies, but we think he's a good, trusted individual.' And to me, in politics that is way too partisan, that was probably the best endorsement that anyone could get,” Warner said.

Warner also talked about the changing political landscape of Virginia. He pointed out Virginia is front and center at this year's convention, showing how it has become a battleground state over the past several election cycles.

Democrats now hold all statewide offices in the commonwealth.

Warner thinks the party is thriving because it has proven Democrats can be bipartisan and look for common ground with Republicans.
