Democratic National Committee Chief Executive Officer Jess O’Connell is leaving the organization less than a year after joining the committee, she announced to the staff in an email on Monday night.

The departure of O’Connell — a longtime campaign pro who came to the DNC from EMILY’s List in May — comes at as the DNC works to rebuild under Chairman Tom Perez after years of neglect. It had struggled to raise money in 2017, but invested in local races in recent months.

“I’m proud to have helped to rebuild our party at a time when we needed it most. I am grateful to Chairman Tom Perez for the opportunity to serve during such a pivotal moment in our history as we fight with everything we’ve got to protect and promote Democratic values and to elect more Democrats nationwide,” O’Connell wrote in her email to the DNC staff, according to a copy obtained by POLITICO.

Perez sent a follow up email thanking O’Connell, and explaining that she will stay on in the coming weeks. He has begun searching for a replacement already, and she is expected to remain working from the Capitol Hill offices through March, said a Democrat familiar with the situation.
