State Democratic Party Chairman Rick Palacio acknowledged an error, telling The Denver Post in a story published Tuesday that a volunteer in Denver had misreported results from 10 precinct locations.

"It was basically a reporting error on caucus night," he said, dismissing suggestions of fraud.

Palacio suggested the campaigns received the correct data days after the caucus in an email, according to the Post, which reported that the party did not move to correct the public record.

Clinton's campaign realized the discrepancy between the public data and the official results and discussed it with the party last Friday, Palacio told the Post.

Palacio said he didn't tell the Sanders campaign about the error "because it didn't necessarily affect (them). It was our mistake that ended up affecting the estimation of Hillary's campaign."
