The announcement came after the party had provided a partial update earlier in the day, attributing the prior night’s mangling of the release of caucus data to a “coding issue” that had since been fixed.

The lack of timely results has infuriated presidential campaigns, scuttling an accurate narrative out of the first-in-the-nation caucus state and forcing candidates to move on to New Hampshire without the knowledge of who exactly won Iowa and in what order.

Campaigns were apoplectic Monday, demanding answers from the party as time ticked away and they feared every moment lost would undermine the credibility and impact of the results.

The issues stemmed from a glitch with a reporting app, which precinct chairs complained was not functioning properly. The party on Tuesday said the app was reporting only partial data.

“We have determined that this was due to a coding issue in the reporting system. This issue was identified and fixed,” Iowa Democratic Party Chair Troy Price said in the statement Tuesday morning. “The application’s reporting issue did not impact the ability of precinct chairs to report data accurately.”

Staff then had to enter data manually. “This took longer than expected. As part of our investigation, we determined with certainty that the underlying data collected via the app was sound," the statement said.

Already on Monday night, campaigns were questioning the veracity of the data collected. Joe Biden’s general counsel sent a letter to the party saying no results should be released before “acute failures” in reporting were addressed.

“We believe that the campaigns deserve full explanations and relevant information regarding the methods of quality control you are employing, and an opportunity to respond, before any official results are released,” the campaign’s attorney, Dana Remus wrote. “We look forward to hearing from you promptly.”
