The Democratic National Committee’s new finance chair, Chris Korge, affirmed his commitment to neutrality in the presidential primary in response to scrutiny of past comments criticizing Sen. Bernie Sanders (I-Vt.) and a donation to the campaign of Sen. Kamala Harris (D-Calif.).

At issue are comments Korge has made about Sanders prior to accepting the job at the DNC. He retweeted a message in December calling Sanders “dangerous to the future of the Democratic Party.”

“I have worked tirelessly to help the Democratic Party, and have been proud to support a wide array of Democratic candidates,” Korge said in a statement. “I’m fully committed to the DNC’s neutrality policy and I look forward to raising the funds necessary to help whoever our Democratic nominee is.”
