Democratic National Committee Chairman Tom Perez called on Thursday for an immediate "recanvass" of Iowa as concerns mounted about the integrity of the results from Monday's first-in-the-nation nominating contest in the state. "Enough is enough," Perez wrote in a post on Twitter. "In light of the problems that have emerged in the implementation of the delegate selection plan and in order to assure public confidence in the results, I am calling on the Iowa Democratic Party to immediately begin a recanvass." TWEET Perez's tweet came hours after The New York Times said that its analysis of the Iowa results revealed inconsistencies in data from more than 100 precincts. In a follow-up tweet, Perez said a recanvass "is a review of the worksheets from each caucus site to ensure accuracy."

Daniel Wessel, a spokesperson for the DNC, referred CNBC to the Iowa Democratic Party's manual, which defines a recanvass as a "a hand audit of Caucus Math Worksheets and Reporting Forms to ensure that they were tallied and reported in the telephone intake sheets and caucus reporting application correctly." The Iowa Democratic Party appeared to rebuff Perez's demand, and said in a statement that it is prepared to conduct a recanvass if it is requested by a presidential candidate. Perez's tweet is sure to inject even more uncertainty into a process that has threatened to upend the public trust in the results from Iowa's caucuses, which historically have shaped the narrative of Democratic presidential primaries. Monday's caucuses have been plagued with problems, including the failure of an app that was supposed to be used for the reporting of results from nearly 1,700 precincts. The state party has insisted that despite the app's problems, the underlying data is accurate. It has slowly released results throughout the week. As of Thursday morning, the party released data from 97% of precincts that showed former South Bend, Indiana, Mayor Pete Buttigieg and Sen. Bernie Sanders, I-Vt., vying for the lead.
