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.

The new leader of the Democratic National Committee says party officers should be banned from taking sides in primaries.

Vice Chair David Hogg said his organization “Leaders We Deserve” will focus on challenging more than a dozen Democratic incumbents in the next election cycle. He said the group will focus on mobilizing a younger generation of leaders geared towards change amid new policies implemented under the Trump administration.
