Here is the latest Iowa news from The Associated Press at 3:40 a.m. CST

DES MOINES, Iowa (AP) — The Iowa Democratic Party has released additional results from Monday night’s presidential caucuses. After a daylong delay, the party has now made public 71% of results from all 99 Iowa counties. The new numbers released late Tuesday do not change the state of play for the candidates. Former South Bend, Indiana, Mayor Pete Buttigieg holds a slight lead over Vermont Sen. Bernie Sanders. Massachusetts Sen. Elizabeth Warren, former Vice President Joe Biden and Minnesota Sen. Amy Klobuchar trail behind. It is too early for The Associated Press to declare a winner.

DES MOINES, Iowa (AP) — Iowa’s coveted position as the first-in-the-nation presidential nominating contest faces its most daunting challenge in light of problems that prevented the state Democratic Party from reporting results Monday night. The caucuses were already facing plenty of headwinds amid criticism that the overwhelmingly white state isn’t representative of the country’s diversity. The Iowa Democratic Party said Monday night that results were indefinitely delayed because of “quality checks” and “inconsistencies” in some reporting. It’s an embarrassing complication that added a new layer of doubt in the caucus process that has come under increasing criticism.
