Obama and Clinton clash over 'nasty' campaigning

The rival US presidential campaigns of Hillary Rodham Clinton and Barack Obama traded accusations of nasty politics over Hollywood donor David Geffen, who once backed former president Bill Clinton but now supports his wife’s top rival.

The Clinton campaign demanded that Obama denounce comments made by the DreamWorks movie studio founder, who told New York Times columnist Maureen Dowd in yesterday’s editions that while “everybody in politics lies,” the former president and his wife “do it with such ease, it’s troubling".
