Trump: I'll probably sue over voter fraud in Iowa

Asked if he would sue, Trump said, “I probably will, what he did is unthinkable. He said the man has left the race and he said it during the caucus. And then when the clarification was put out by Ben Carson saying it’s untrue, they got the statement and they didn’t put it out.”

“They apologized after the caucus was over, how does that help?” added Trump.

Trump, echoing accusations he made earlier on Wednesday in a series of tweets, called Cruz’s action “total voter fraud.”

“It’s a total voter fraud when you think of it and he picked up a lot of those votes and that’s why the polls were so wrong, because of that,” continued Trump. “I couldn’t understand why the polls were wrong.”
