The Democratic National Committee is cracking down on gun control advocate and DNC vice chair David Hogg’s plans to spend millions primarying incumbents he deems “ineffective.”

PHOENIX (AP) — Democratic National Committee Chair Ken Martin said Thursday that party officers should be banned from taking sides in primaries, countering DNC Vice Chair David Hogg’s plan to raise money for candidates challenging Democratic incumbents.

Democratic National Committee Chair Ken Martin said Thursday during a party call that efforts by newly elected vice chair David Hogg to fund primary challenges for "older, establishment" Democrats in "safe districts" will not be tolerated.
