ROCK THE VOTE

Nick, Joe and Kevin Jonas make a power trio during the kids' concert on Monday, hosted by Michelle Obama and Vice President-elect Joe Biden's wife Jill Biden. "It was awesome," Joe said of seeing the Obamas and the Bidens dancing in the front row. "I had to get them up on stage and celebrate together."
