With a new knee, Webb's still considering 2016 plans

(CNN)Jim Webb, a former Virginia senator contemplating a run for president, was released from the hospital Tuesday after having his left knee replaced.

Webb, a decorated Vietnam War veteran, needed the surgery because of a combat related injury during the war.
"Jim has just undergone a full knee replacement as a consequence of shrapnel wounds received from an enemy grenade," said Craig Crawford, Webb's spokesman. "He is out of the hospital and recovering quite well. The upside is he can catch up with the new season of 'Downton Abbey.'"
Webb, who served in the Senate from 2007-2013, announced in November he was actively exploring a bid for the Democratic presidential nomination.
    "True leadership makes a difference," Webb said in straight to camera statement announcing his intention to consider a presidential run. "Results can be obtained, even in a paralyzed political environment, and in fact I believe we can un-paralyze the environment and re-establish a transparent, functioning governmental system in our country."
    Crawford, who released details of the operation Friday, said that doctors told Webb his recuperation would last a few weeks.
    Hillary Clinton, who served alongside Webb in the Senate, is also considering a bid for the Democratic presidential nomination as is Vermont Sen. Bernie Sanders and former Maryland Gov. Martin O'Malley.
