Democratic Congressional Campaign Committee Chairwoman Cheri Bustos announced the appointment of a new interim executive director Monday as she seeks to quell internal jousting between lawmakers and the committee about diversity representation in its upper ranks.

“Today has been a sobering day filled with tough conversations that too often we avoid, but I can say confidently that we are taking the first steps toward putting the DCCC back on path to protect and expand our majority, with a staff that truly reflects the diversity of our Democratic caucus and our party,” Bustos said in a statement.

DCCC leadership had come under fire from some lawmakers for not including more diverse staffers among its top brass.

By Monday evening, multiple news sources reported an exodus of top aides, including some central to the committee’s work towards taking the House in 2018.

The chaos comes on the heels of executive director Allison Jaslow’s resignation. She first announced her departure at all-staff meeting on Monday, and confirmed the news in a statement posted to Twitter.
