Democratic Congressional Campaign Committee Chairman Cheri Bustos, facing mounting pressure from the party’s left, has agreed to a DCCC meeting with progressive groups who want her to ditch a controversial policy meant to shield incumbents from primary challenges, according to representatives from the progressive group Our Revolution.

Bustos has so far given no public indication that the committee would relax its stance against working with consultants and other operatives who assist candidates who challenge incumbent House Democrats.

But progressive activists who have spoken with her in recent days said they were heartened that she has left the door open to the discussion.

“It’s important to show her willingness to carry on conversations,” said Richard Rodriguez, a national board member of Our Revolution, who met with Bustos Thursday. “I’m sure she is also feeling some political pressure.”

He pointed out that the meeting coincided with news that more than 40 College Democrats chapters had joined a boycott of the DCCC over the vendor policy.
