White House Press Secretary Jay Carney doesn't know if any of President Obama's staffers were involved in the Secret Service prostitution scandal; he can only say that he hasn't heard that they were.

Carney doesn't seem to be trying to find out. "Not that I'm aware of," he answered today when asked if anyone had checked with the White House staffers to make sure they weren't involved. Yesterday, he replied to the same question with essentially the same answer. Today, he refused to discuss "random rumors" that staffers in the Executive Office of the President were involved in the prostitution party.

"I have no reason to believe, I do not know otherwise, that this did not involve anything but the agents and the military personnel," Carney said during the press briefing today.  "I really don't have anything more for you on that."

He had time to look into the question, though. "You’re positive there were no White House Executive Office of the President employees involved?" he was asked yesterday. Carney replied with the non-definitive "I have not heard otherwise."

Today, Carney refused to "speculate about every rumor that you may have heard from either anonymous sources or just the internet."
