Tim Griffin returns to the RNC

From NBC's Mark Murray
Republican political operative and Karl Rove protégé Tim Griffin -- who served as an interim US attorney in Arkansas before the US attorneys firing scandal forced him not to seek confirmation to that post -- is returning to the Republican National Committee to handle the party's opposition research against Obama.

Griffin served as the RNC's research director during the 2004 presidential election.

"He's one of the best political operatives in the country," said a Republican source who confirmed to First Read Griffin's hire at the RNC.

*** UPDATE *** Another Republican operative pushes back slightly that Griffin's role will focused solely on oppo-research, adding that his role is still being worked out.
