Republican presidential candidate Ted Cruz on Wednesday afternoon took to Twitter to respond to voter fraud allegations made against him by rival Donald Trump, dismissing the comments as a “Trumper tantrum.”

“Yet another #Trumpertantrum,” Cruz tweeted. “@realDonaldTrump very angry w/the people of Iowa. They actually looked at his record.”

{mosads}Earlier Wednesday, Trump used social media to accuse the Texas senator of committing fraud in order to win Monday night’s Iowa caucuses.

“Ted Cruz didn’t win Iowa, he stole it,” the real estate mogul told his followers. “That is why all of the polls were so wrong and why he got far more votes than anticipated. Bad!”

In the run-up to the caucuses, Cruz was scolded by Iowa’s secretary of State for a controversial mailed disguised to look like an official government form reprimanding voters for not turning out to vote.

And after his decisive victory, Cruz was further rebuked by Ben Carson and his campaign for spreading a rumor that the retired neurosurgeon was dropping out, allegedly in an effort to convince Carson voters to switch candidates.

“Based on the fraud committed by Senator Ted Cruz during the Iowa Caucus, either a new election should take place or Cruz results nullified,” Trump tweeted, later adding: “The State of Iowa should disqualify Ted Cruz from the most recent election on the basis that he cheated- a total fraud!”
