In the clip, Kaine recounts his time as governor of Virginia, promises to work across party lines, and never mentions his time at the partisan DNC.
"I'm running for the United States Senate because America has big challenges, and I'm convinced that Virginia has answers to help strengthen our nation," Kaine says in the video.
Kaine would enter the race to succeed Democratic Sen. Jim Webb, who announced in February he will retire from office after just one term.
