U.S Senator Edward Kennedy (D-MA) waves as he walks out of Massachusetts General Hospital in Boston, Massachusetts, in this May 21, 2008 file photo. Kennedy returned to the U.S. Capitol on July 9, 2008 for the first time since his brain surgery last month, ready to provide fellow Democrats the needed 60th vote to clear a stalled-Medicare bill opposed by the White House.
