DES MOINES, United States, Feb. 4 (Xinhua) -- The "majority of results" of Democratic caucuses in the U.S. state of Iowa Monday night will be released by 4 p.m. Central Time on Tuesday (GMT 2200), according to an Iowa Democratic Party (IDP) official.
IDP Chair Troy Price told Democratic campaigns in a call that "more than 50 percent of all results" will be released.
A "coding issue" in a mobile app used to collect data for the Democratic caucuses was responsible for a delayed announcement of results, the state party official said in a statement.
"While the app was recording data accurately, it was reporting out only partial data," he said. "We have determined that this was due to a coding issue in the reporting system."
Iowa, a state in the Midwestern United States, held Democratic and Republican caucuses Monday night, kicking off the 2020 presidential primary.
The caucuses brought tens of thousands of Iowa's registered voters to churches, public libraries, and school gyms for discussions of their presidential preferences.
Sitting President Donald Trump won the Republican caucuses, in which participants cast a vote to indicate their support, in a largely symbolic vote as he was facing no significant challenge.
On the Democratic side, there are 11 contenders seeking the party's presidential nomination.
Former U.S. Vice President Joe Biden, Senators Bernie Sanders, Elizabeth Warren, and Amy Klobuchar, and Indiana's former South Bend Mayor Pete Buttigieg, addressed supporters after the Democratic caucuses late Monday night despite the delay of results.
