"You know what I wanted to. I wanted to hit a couple of those speakers so hard," Trump said. "I would have hit them. No, no. I was going to hit them, I was all set and then I got a call from a highly respected governor."
Trump didn't immediately clarify what he meant, but he said he was made particularly upset by an unspecified person he called a "little guy."
"I was gonna hit one guy in particular, a very little guy," he said. "I was gonna hit this guy so hard his head would spin and he wouldn't know what the hell happened."
"By the way, if they hacked, they probably have her 33,000 emails. I hope they do," Trump told reporters Wednesday morning during a press conference at his golf club in Doral, Florida. "They probably have her 33,000 emails that she lost and deleted."
His campaign immediately tried to walk back his remarks.
Today, he wrote off what he said as sarcasm on Fox News.
"Of course I was being sarcastic," the Republican presidential nominee said on "Fox & Friends" this morning.
"I was going to say it before. What Bernie should have done instead of selling out to the devil which is what he did, Bernie should have quietly let everything happen, have his protest. He’ll lose, have his protest, go home. He would have gone home a hero," Trump said. "Really, now he's on the other side of the equation except for one thing, trade. He's the only one that gets it."
Trump repeated the sentiment at a rally hosted in Cedar Rapids several hours later, and expressed his desire to "hit this [little] guy so bad."
He said that he was urged to think of his fight against "Crooked Hillary" instead, and that he was advised "don't punch down."
