MINNEAPOLIS, Minn. —The Democratic National Committee‘s Rules and Bylaws Committee passed an amendment Tuesday evening prohibiting officers and staff from meddling in Democratic primary elections.

The vote was previously meant to rebuke and block David Hogg, a former DNC vice chairman, from endorsing younger candidates against elder incumbents. But before the DNC summer gathering this week, Hogg declined to seek reelection when it became increasingly clear he would lose.
