PHILADELPHIA (CBS) — More trouble for Seth Williams more charges filed against Philadelphia’s top law official by the acting US Attorney in New Jersey.

Williams was indicted in March on 23 bribery and corruption charges, but that count is now up to 29.

In a superseding indictment, government officials allege District Attorney Seth Williams used campaign money to buy birthday presents for his girlfriend, along with massages, facials and clothing from a health club.

“All of the information which these charges are based upon, the US Attorney’s office has had for years,” said Williams Attorney Tom Burke.

He denies his client did anything wrong and says calls it a ploy by the prosecutors.
