Donald Trump lamented Friday that Hillary Clinton did not congratulate him during her acceptance speech at the Democratic National Convention.

During a rally in Colorado Springs, Trump said he tuned in to Clinton’s speech “out of curiosity” to see if Clinton would mention his name and was disappointed she didn’t congratulate him for winning the GOP nomination.

“I was curious to see whether she’d do a class act and not mention my name,” Trump said. “Or mention it with respect, like, say, ‘I’d like to congratulate my Republican opponent for having done something that nobody has ever done in the history of politics in this nation.'”

Trump went on to say that he has been the more civil one in campaigning against Clinton because he does not join in on chants of “lock her up” when people yell them at his rallies, but that his kindness has run out.

“Every time I mention her, everyone screams ‘lock her up, lock her up’,” he said. “And you know what I do? I’ve been nice. But after watching that performance last night, such lies, I don’t have to be so nice anymore. I’m taking the gloves off, right? Yes? Take the gloves off. Take the gloves off. Right? Taking the gloves off. Just remember this, Trump is going to be no more Mr. Nice guy.”
