Much of Ken Martin’s four months as head of the Democratic National Committee have been engulfed in a feud with David Hogg, the Gen Z activist who vowed to back primary challengers to Democratic incumbents in conflict with other party leaders.

Hogg's efforts to primary Democrats with younger candidates angered members of the party who disagreed with DNC leadership meddling in primaries.

Progressive activist David Hogg on Wednesday announced he will not be running in the Democratic National Committee’s upcoming election, leaving his post as vice chair following months of tense party infighting over his plan to take down Democratic incumbents.
