Newt's daughter: He's "very serious" about White House run

During an interview with Human Events, Jackie Gingrich Cushman, who has a new book out (for which Newt writes the foreword), says:

He’s very serious. He’s much more serious than he ever has been. And I can tell that because we actually sat down -- just the two of us -- for two hours recently. And I don’t think that’s happened since I had children.
