PHOTO: Betty White Visits Barack Obama At The White House

While visiting Washington, D.C., to make a speech at the Smithsonian museum, Betty White, 90, made a pit stop at the White House, where she snapped a photograph with President Barack Obama in the Oval Office and walked around the grounds with the first dog, Bo.

Earlier this year, Obama filmed a video greeting for White's 90th Birthday special, in which he jokingly asked to see a copy of the Emmy winner's birth certificate.
