The Democratic National Convention kicks off today in Philadelphia after a weekend of headlines – some welcomed by the party, some not so much.

Some of them indicated favoritism toward Clinton as she battled Bernie Sanders for the party nomination. We talk about the email controversy, the vice presidential candidate and what to expect at the convention this week.
