The Iowa caucuses turned into a chaotic mess that kept state and national Democrats up late into the night as state party leaders failed to declare a winner and officials were unsure how they would do so in the future.

That confusion brought condemnation on both sides: Republican Donald Trump said he would ignore what results emerge from the caucus, while Democratic Sen. Bernie Sanders from Vermont called the results “disgraceful.”

The crisis arose at the Democratic caucuses, with some holding up candidates who had not been declared the winner in years.

“What the Iowa Democratic Party didn’t do is to wait and see whether anybody won,” said Rep. Adam Schiff (D-Burbank), who described it as “mind-boggling.”

“This sort of thing is the classic dysfunction of the nominating process,” Schiff said. “These candidates have been handicapped with disparate results. We must have consensus by some time in March. But that’s only going to happen with agreement on the rules, on how we rank delegates.”

Caucuses begin at 7:30 p.m. CST on the West Coast.
