Bernie Sanders’ presidential campaign released internal reporting numbers from about 40 percent of precincts that participated in the Iowa caucus early Tuesday.

The numbers released by Sanders’ campaign came hours after the state’s Democratic Party said it could not release official results because of “inconsistencies” in the numbers.

Sanders’ internal figures showed the Vermont socialist leading top rivals with more than 29 percent of caucus support.

According to the numbers, Sanders was trailed by former South Bend, Indiana, Mayor Pete Buttigieg, who had more than 24 percent. Close behind him was Sen. Elizabeth Warren, who had support from more than 21 percent.

Former Vice President Joe Biden was in a far-flung fourth place, according to the numbers, with just 12 percent support in the caucus.

“We recognize that this does not replace the full data from the Iowa Democratic Party,” Sanders’ senior adviser Jeff Weaver said in a statement.

“But we believe firmly that our supporters worked too hard for too long to have the results of the work delayed.”

Biden’s campaign attorney said in a letter Monday night that they want the Iowa Democratic Party to provide the candidates with information about the error before any results are released.

“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,” Dana Remus, general counsel for the Biden campaign, wrote in the letter to the party.
