District Attorney: Larry Krasner, a civil rights attorney, beat out a crowded field to win the Democratic nomination for district attorney in Philadelphia.

In the November election, he will face Beth Grossman, a former assistant district attorney and the only Republican on Tuesday's ballot.

In his first briefing as the Democratic nominee, Krasner thanked voters, defended his lack of prosecutorial experience experience and said he would not be beholden to billionaire George Soros, who gave $1.45 million to a political action committee that backed the civil rights lawyer's campaign.

While progressives are cheering Krasner's win, some prosecutors in the District Attorney's Office – of which Krasner was deeply critical in his anti-establishment campaign – were dismayed by the victory, and the leader of the city's police union is slamming Krasner supporters who chanted a profane slogan about the union at the candidate's victory party.
