White House Press Secretary Jay Carney said Monday that an internal review found no indication of any involvement by White House advance staff in the prostitution scandal rocking the Secret Service and the Defense Department.

The review, conducted by the White House counsel’s office, began Friday and concluded during the weekend, Carney said, and found “no indication of any misconduct.”

Carney declined to provide details of the review.

“I’m not going to give you a blow-by-blow,” he said.

Carney’s statement came after Sen. Chuck Grassley (R-Iowa), asked last week whether members of the White House’s advance team were under investigation and if not, why not. Grassley is the ranking member of the Judiciary Committee.

Senate Homeland Security and Governmental Affairs Chairman Joe Lieberman (I-Conn.), who caucuses with Democrats, endorsed Grassley’s call on “Fox News Sunday With Chris Wallace”: “The White House ought to be conducting its own internal investigation of White House personnel who were in Cartagena, just to make sure that none of them were involved in this kind of inappropriate behavior.”
