WASHINGTON (CNN) -- It's not often the White House press corps is the envy of your average 13-year-old, but then again, it's not every day the Jonas brothers stop by.
Nick, Joe and Kevin Jonas make up the hugely successful teen boy band aptly named the Jonas Brothers. They came to the White House to attend a briefing on diabetes and tape a public service announcement about National Parks.
They were also in town to unveil their wax figures at Madam Tussauds Wax Museum in Washington.
The brothers, who released their third album this summer, left their mark at the White House by signing their names on the wall of the swimming pool that used to be in the basement of the White House. The wall has been signed by first lady Laura Bush and Bono, which Joe Jonas found, among many others. Watch the brothers sign their names »
"There's other names up there that are just astounding, some of our favorite artists and politicians," Joe Jonas said. "But it's going to be really cool to see that in 10 years, 20 years from now."
But some journalists, roughly 20 years older than the pop-star siblings and expecting a quiet day, were taken aback by the commotion.
"Who?" asked one journalist on being informed of the visit. In the press room, only those with young teens or an interest in celebrity news had ever heard of them.
Vice President Dick Cheney, on the other hand, was hip to the trio. He may not be a celebrity news hound, but he definitely knows what his grandchildren like. Cheney told CNN's Ed Henry he brought his three granddaughters to the White House to meet the brothers.
The brothers also attended a briefing on diabetes in the Eisenhower Executive Office Building next door to the White House. Nick Jonas, who has diabetes, said he is inspired by kids he meets also afflicted with the disease.
"A lot of kids first feel lonely when they first get diagnosed with diabetes. I'm just so encouraged at the end of the day because all I'm trying to do is make it through another day managing diabetes," Nick Jonas said. "They're just doing the same thing. We're all there for each other."
The public service announcement they taped on the South Lawn encourages children to be more active and to enjoy America's national parks.
"We on stage run around constantly for about an hour-and-45 minutes and we know what that can do, you just feel great at the end of the night and when you wake up in the morning," Kevin Jonas said.
Nick said he hopes the service announcement encourages "kids to get our there and go to the parks and really, really enjoy the outdoors. And I know that was really important to us when we were kids so try to make it important to them too."
At a stakeout where White House reporters typically grill members of Congress and cabinet secretaries, the Jonas brothers were grilled about who they support in the presidential race.
Kevin Jonas said they do not plan to endorse any particular political campaign, adding, "but we do -- me and Joe are both of voting age -- so we do endorse voting, getting to know the issues, learning about the candidates ... and [making] a decision for yourself."
