"A man has been arrested for throwing a pie in the face of Sacramento's mayor following his speech at a charity dinner. Sacramento Mayor Kevin Johnson had given a speech at the Seeds of HOPE dinner at Sacramento Charter High School Wednesday night before Sean Thompson, 32, came up and grabbed the former NBA star. Thompson then shoved the pie in Johnson's face, the mayor's Chief of Staff Crystal Strait said. Strait said the mayor defended himself against the man, but she would not give details. The mayor tweeted that he's 'doing fine' and added: 'Thank you to Sac PD for being there.' "
