"What these organizations should not be doing is doing negative attacks on Democratic candidates," Sanders told The Associated Press in an interview.
"That just continues the process of debasing the Democratic system in this country and is why so many people are disgusted with politics."
Sanders comments came in reference to the DCCC's decision to publish opposition research against Democrat Laura Moser ahead of the March 6 congressional primary for Texas' 7th district.
Moser, an activist endorsed by Sanders' group Our Revolution, will now head to a runoff election against Democrat Lizzie Pannill Fletcher in May. Neither candidate received a majority of the vote in the Tuesday primary.
