Pete Buttigieg and Bernie Sanders took the lead as the first results in the Iowa Democratic caucus were finally released, a day after technical issues caused chaos.

Iran Press/America: With 62% of precincts reporting, Pete Buttigieg and Bernie Sanders appear to lead the pack. Until the complete results are announced, it’s unclear how Iowa’s 41 delegates will be allotted among the winners.

Buttigieg is in the lead with 26.9% of the state delegates, Bernie Sanders has 25.1%, Elizabeth Warren has 18.3% and Joe Biden has 15.6%, The Guardian reported.

That ordering could change once the remaining 38% of precincts reporting results.

Sanders secured the popular vote, with Buttigieg and Warren trailing slightly behind.

With 62 percent of results released, Pete Buttigieg, the former mayor of South Bend, Indiana, was leading the field on state delegate equivalents, with Vermont senator Bernie Sanders second.

Elizabeth Warren the Massachusetts senator, was third in both, followed by former vice-president Joe Biden and Amy Klobuchar, the Minnesota senator, in fifth.

The partial results were announced as the chairman of the Iowa Democratic Party, Troy Price, apologized for the problems which have inspired mockery from President Donald Trump and others.

Price promised an independent investigation into what happened, saying: "We've been working day and night to make sure these results are accurate."

Officials blamed the embarrassing hold-up on inconsistencies related to a new mobile app used for voting in Iowa. 101/211
