Republican Sen. John Ensign of Nevada says the Justice Department is no longer investigating whether he violated the law in an attempt to cover up an affair with a former campaign aide.
The Senate ethics committee, however, is still reviewing the matter, CBS News Capitol Hill Producer John Nolen reports.
Jennifer Cooper, a spokesperson for Ensign, said the senator and his staff cooperated with the investigation and are pleased he is no longer a target.
"It's important that the truth in this matter is finally coming to light," she said. "Senator Ensign looks forward to continuing his hard work on behalf of the people of Nevada."
After acknowledging the affair last year, Ensign fell under scrutiny for possibly violating congressional rules by helping the aide's husband find work as a lobbyist. On top of that, Ensign's parents gave the his mistress and her husband a payment of $96,000 that they described as a gift.
The revelations prompted some Nevada Republicans to, but the senator has said he will seek re-election in 2012.
