The executive director of the Allegheny County Democratic Committee has resigned from his post, just weeks after being hired, amid outcry over his social media posts.

Nancy Patton Mills, who hopes to be chosen as the next chair of the state Democratic Committee next week, suffered a rebuke in her own home county on Saturday: Despite the support of Gov. Tom Wolf and other top Democrats, she lost the race for Allegheny County Democratic chair to Eileen Kelly by a two-to-one margin.
