 Meanwhile, former California U.S. Senator Barbara Boxer is dismissing calls for Joe Biden to step aside. KQED Politics Editor Scott Schaefer reports. Last week, Boxer told the LA Times that Biden had two weeks to right the ship following a debate performance that sent many Democrats into panic mode. But now, Boxer tells KQED that he's convinced her, through media interviews and public appearances since then, that he's up to the task of defeating Donald Trump.
