On the Republican side, Senator John McCain attempted to distance himself from a New York Times report that alleged some of his aides suspected improper conduct between him and a younger female lobbyist.
McCain, who with 976 delegates compared to nearest rival Mike Huckabee's 245 looks set to capture his party's nomination, refused to answer any more questions on the topic on Friday, after denying any untoward relationship with the woman.
The lobbyist's firm also rejected the allegations.
But the controversy stirred anew on Saturday, as Newsweek, the Washington Post and the New York Times reported on contradictions in McCain's statements about his contacts with firms associated with the lobbyist.
