U.S. Vice President Joe Biden (C) shares a laugh with outgoing White House Press Secretary Robert Gibbs (R) and Director of White House Communications Dan Pfeiffer in the audience after U.S. President Barack Obama introduced William Daley as the new White House Chief of Staff in the East Room of the White House in Washington, January 6, 2011. Obama on Thursday named J.P. Morgan Chase executive Daley to be his new White House chief of staff, retooling his team with a politically savvy businessman at the helm. Gibbs, one of Obama's closest aides, said on Wednesday he will resign and become an outside adviser for Obama's re-election campaign in a major staff shake-up. REUTERS/Jason Reed
