The Democratic National Committee CEO abruptly stepped down from her post after less than one year on the job, according to multiple reports Monday night.

Veteran operative Jess O’Connell had just taken the party reins this past May, and was tasked with stabilizing party operations in the wake of a disastrous 2016.

The party was in shambles following Donald Trump’s stunning upset win and charges of DNC favoritism for eventual presidential nominee Hillary Clinton.

“Rebuilding the party will take time. While it isn’t an easy task, we developed a strategy, we implemented it, and we won races up and down the ballot in 2017,” O’Connell said in a statement to NBC News.

“While I’ve made the decision to pass the baton, our work remains far from over and under Tom Perez’s leadership and direction, our party will continue to build on the progress we’ve made in 2017.”

DNC Chairman Perez, who won his post just 11 months ago, thanked O’Connell for leading Democrats to a string of off-year wins in 2017.

“Jess O’Connell joined the DNC at a time when our party needed it the most,” Perez said in a statement.

“She helped build our ‘Every Zip Code Counts’ strategy, oversaw unprecedented programming and support for state parties and campaigns, renewed our focus on data and technology, and helped lead us to 100+ victories in elections all across the country in 2017. Jess laid the groundwork for an infrastructure to win in 2018, 2020 and beyond.”
