Email fallout: 3 Democratic National Committee resignations

WASHINGTON (AP) — The chief executive of the Democratic National Committee and two other top officials have resigned in the wake of an email hack that embarrassed the party on the eve of its presidential nominating convention.

The resignations are the latest fallout from the hacked emails, which exposed an apparent lack of neutrality in the primary race between Hillary Clinton and Bernie Sanders, with some party officials disparaging Sanders.

A cybersecurity firm they employed found traces of at least two sophisticated hacking groups on the Democrats' network — both of which have ties to the Russian government.
