Two advisers leaving Robert Grey's campaign
Two seasoned campaign advisers have left Robert Grey's mayoral campaign in a shakeup just two months before the election.
White House press secretary Robert Gibbs, one of President Barack Obama's top advisers, is resigning to become an outside political adviser for Obama's re-election campaign as part of a major staff shake-up Gibbs, 39, a fierce loyalist and defender of the president during near-daily White House news briefings, will leave in early February, aides said.
