A week after Democratic National Committee Debbie Wasserman Schultz's ouster over a controversial trove of hacked emails and documents, the scandal claimed three more casualties Tuesday as other top staffers departed the committee.

CEO Amy Dacey, CFO Brad Marshall and communications director Luis Miranda all left the DNC, effective immediately, according to a statement from the committee.

"Thanks in part to the hard work of Amy, Luis, and Brad, the Democratic Party has adopted the most progressive platform in history, has put itself in financial position to win in November, and has begun the important work of investing in state party partnerships," said interim chairwoman Donna Brazile. "I'm so grateful for their commitment to this cause, and I wish them continued success in the next chapter of their career."

Just before the Democratic convention in Philadelphia last week, Wikileaks posted a trove of documents from the DNC, many of which showed internal bias against Bernie Sanders during the Democratic primary.

As a result, Sanders and others called for Wasserman Schultz to resign, which she did that Monday. The furor over the leaked emails was strong enough that Wasserman Schultz didn't even gavel in the convention--and was booed by delegates from her home state of Florida at the delegation's daily breakfast.

To replace the departing staffers, Brazile announced a transition team that will help fill key roles at the DNC until a new chair is chosen early next year. Tom McMahon, a former executive director at the DNC who served under former chairman Howard Dean, will chair the transition team and help with general-election efforts. Also joining the DNC on an interim basis is Doug Thornell, a Democratic strategist at SKD Knickerbocker in DC; he'll serve as a senior adviser.

Brandon Davis, who came on board at the DNC in June as the chief of staff and has been coordinating efforts with the Clinton campaign, Brazile announced, will continue in his new position.
