In the new results, Buttigieg has 562.954 state delegate equivalents and Sanders has 562.021 state delegate equivalents out of 2,151 counted. That is a margin of 0.04 percentage points.

The Associated Press has reviewed the updated results and will not call a winner, given remaining concerns about whether the results as reported by the party are fully accurate. The Feb. 3 caucuses were beset by technical glitches that led to a delay in reporting the results, inconsistencies in the numbers and no clear winner.

The party plans to certify the results on Saturday. At that point, the caucuses will formally end, and no further changes to the results will be made.
