Donald Trump on Thursday morning refused to acknowledge whether his relentless attacks on a Gold Star family were a “mistake,” but he also avoided launching into a full defense of his comments.

“You’ll have to define what a ‘mistake’ means. We’re not here to talk about that. We’re here to talk about economics,” Trump said on CNBC when asked if his attacks on the Khan family were a “mistake.”

He then refused to talk about the situation further.

“It’s been put to bed for a long time, and I don’t think there’s any reason for you to reopen it,” Trump said.

He was also asked to address his “Second Amendment people” line, which he insisted was a very clear comment about voting.

“Well, on the Second Amendment, everybody came to my defense, because there was nothing said wrong. I’m talking about the power of the voter,” he said on CNBC. “Only the haters tried to grab onto that one, and it was very unsuccessful.”
