Republicans may ask for a special prosecutor in the quid-pro-quo allegations that the White House offered Rep. Joe Sestak a plumb administration job if he didn’t run against fellow Pennsylvania Democrat Sen. Arlen Specter in their state’s primary.

The possibility that Rep. Darrell Issa, R-Calif., might press for a formal review arose after The White House counsel’s office missed a deadline, which already had been extended, to answer questions from House Republicans about Sestak’s statements that the White House offered him a job if he left Specter unchallenged, according to CNSNews.com.

If the White House made such an offer, it could be a federal crime, according to legal experts and members of Congress. Specter, a former district attorney, has said it could constitute bribery, CNSNews said.
