- The DNC kicks off in Philadelphia today as its chair says she's stepping down.  Debbie Wasserman Schultz says she's resigning as Democratic Party chairwoman at the end of this week's convention.  The Florida Congresswoman has been under fire following the publication of hacked emails suggesting the Democratic National Committee favored Hillary Clinton in the presidential primaries.  That prompted runner-up Bernie Sanders to call Sunday for Wasserman Schultz's immediate resignation. Wasserman Schultz still plans to fulfill her duties formally opening and closing the convention in Philadelphia. She also says she will speak at the four-day gathering.  DNC Vice Chair Donna Brazile will serve as Interim Chair through the election.  Hillary Clinton thanked Wasserman Schultz "for her leadership."
