(AP Photo/The Gazette, Brian Ray) (Newser) – If you thought the Secret Service prostitution scandal was harmless, think again; Charles Grassley thinks it's "something that is very, very serious when national security might not be protected properly," he told an Iowa radio station, in a conversation spotted by The Hill. After all, the GOP senator explained, "Who knows who might be using prostitutes? The Russians are famous for that to get information out of us." Grassley is one of a number of lawmakers pressing the White House for more information, like whether any staffers had acted improperly. The White House says its probe has cleared all staffers, but Grassley wants more information. "The issue here isn't just people messing around with prostitutes," he said. "The issue is any national security implications that it might have because of the secrecy and the documents and things of that nature."
