(CNN) – North Carolina Gov. Mike Easley will endorse Hillary Clinton's White House bid, two sources close to the campaign tell CNN.
The endorsement could give the New York senator a boost in the state with one week to go until its crucial May 6 primary. Recent polling suggests Barack Obama currently holds a double-digit lead over Clinton there, though no polls have been released since Clinton’s win in Pennsylvania last week.
Easley is also a superdelegate - one of the party's nearly 800 insiders who will determine which candidate wins the Democratic nomination. Earlier Monday, the Obama campaign announced it had picked up its own superdelegate endorsement, New Mexico Sen. Jeff Bingaman.
