Rep. Brad Miller is endorsing Democratic presidential candidate Barack Obama.
The three-term lawmaker from Raleigh is the third North Carolina superdelegate to pledge support to Obama since the Illinois senator's convincing victory in the state's primary.
Miller says he decided to endorse Obama following an afternoon meeting with the candidate.
Obama now has the support of nine superdelegates from North Carolina. Rival Hillary Rodham Clinton has the support of three state superdelegates, including Gov. Mike Easley.
There are five uncommitted superdelegates remaining. Obama won North Carolina's primary by 14 points on Tuesday.
