While Barack Obama's two daughters have already met Nick Jonas at the Kids' Inaugural Ball, the President finally met the youngest Jonas Brother yesterday. However, that wasn't the only reason Nick was in Washington.

Nick Jonas was diagnosed with diabetes at the age of 13, and is now fighting for diabetes research funding while working for the Juvenile Diabetes Research Foundation. He will testify today in front of the Senate Homeland Security and Government Affairs Committee along with Sugar Ray Leonard and Mary Tyler Moore.

Still, meeting the President was an important experience. He told People on his way to the White House, "I'm excited... This is the first time I'm meeting the president. It's gonna be fun." He caught up with Barack, who was with a group of kids also dealing with diabetes.

The children didn't know Nick was arriving - and they were understandably more excited to greet the teen sensation than talk to Obama. "It was great," Jonas told People outside the Executive Mansion. "He came up and thanked me for meeting his daughters and playing for them. I said, 'It's a pleasure to meet you.' He said, 'It's a pleasure to meet you, too.' Then we took a picture with about 100 kids."
