WASHINGTON – House Speaker Nancy Pelosi said Friday she won't talk any more about her charge that the CIA lied in 2002 about using waterboarding on terrorism suspects. "I have made the statement that I'm going to make on this," she told reporters at a Capitol Hill news conference. "I don't have anything more to say about it. I stand by my comment." But Republicans aren't letting this one slide. Ken Spain, spokesman for the National Republican Congressional Committee, issued a statement after the news conference calling Pelosi a political liability to the Democratic party.
