President Obama interrupted a round of vacation golf and returned hastily to his family's rental home in Hawaii. The Honolulu Advertiser and the Associated Press report that an ambulance was summoned to the vacation home. NPR's Senior Washington Editor, Ron Elving, says a child traveling with the Obama family suffered a cut chin. While the ambulance was called, it wasn't necessary. The child may go to the hospital 'out of an abundance of caution.'
