Presidential candidate Donald Trump has called for a new election in Iowa, accusing the Republican winner, Ted Cruz, of fraud.
Mr Trump pointed to the fact that during the caucus the Cruz campaign told voters rival Ben Carson planned to quit the race, which was not true.
The Cruz campaign apologized to Carson's camp, saying it was a misunderstanding.
Mr Trump also cited Cruz leaflets that accused Iowans of "voting violations".
Paul Pate, the top election official in Iowa, condemned the mailers on Saturday, saying the state does not track or grade individual voters.
Mr Pate said Mr Cruz's mailers "misrepresent Iowa election law" and that they were "not in keeping in the spirit of the Iowa Caucuses," but he stopped short of any official action.
"Ted Cruz didn't win Iowa, he stole it. That is why all of the polls were so wrong and why he got far more votes than anticipated. Bad!" Mr Trump said.
Earlier, he wrote on Twitter that Mr Cruz "illegally" won the caucus, but later deleted the tweet.
