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.

David Hogg said Wednesday he will not fight to hold onto his leadership role in the Democratic National Committee after igniting a firestorm over his push to target long-serving Democrats in safe congressional seats.

David Hogg, who was at the center of controversy over his efforts to primary incumbents in Congress, is leaving the Democratic National Committee.
