Hawk took a brief ride Friday in the White House's grand foyer and the nearby Old Executive Office Building. He had the permission of White House officials, and he posted photos and Twitter accounts on his Web site.
One photo shows Hawk on his skateboard with his hands in the air in what appears to be a hallway.
"...and here is my exit," he wrote in a message on Twitter, which linked to a picture of him skating. "Supposed to return at noon for the First Fathers event if they let me back in."
Hawk posted other insights from his Washington visit on his Twitter page, telling fans about eating Frosted Flakes cereal inside the gates of 1600 Pennsylvania Ave. In another tweet, he says "back at White House, Tweeting live from the Diplomatic Room. Unbelievable."
Hawk later joined other dads, athletes and celebrities at the Father's Day forum hosted by President Barack Obama.
Celebrity chef Bobby Flay helped man the barbecue grills for a White House picnic for the attendees.
