Democratic vice-presidential nominee Tim Walz defended himself Sunday by saying he will “own up” when he misspeaks.

“Fox News Sunday” host Shannon Bream asked him to respond to claims he’s made that have been revealed as not true, such as his wife using in-vitro fertilization instead of intrauterine insemination, being in China during the Tiananmen Square protests and what he did while in the military.

“They know, and I’m very proud of my 24 years in service and my record. I have never disparaged someone else in this, but I know that’s not what [former President] Donald Trump does,” said Mr. Walz, the governor of Minnesota.

“They disparage everyone, give personal attacks. I will own up when I misspeak. I will own up when I make a mistake,” he said.

Mr. Walz called himself a knucklehead for his past misstatements during last week’s vice-presidential debate with Sen. J.D. Vance, Ohio Republican.

“Look, I will be the first to tell you. I have poured my heart into my community, I’ve tried to do the best I can, but I’ve not been perfect and I’m a knucklehead at times,” he said.

On Sunday he said he doesn’t think “people care whether I used IUI or IVF when we talk about this,” they just care about what Mr. Trump said he would take away.

“I think folks know who I am; my constituents here in Minnesota have elected me eight times, they know where I’m at and I’m proud to be on the ticket and we’ll deliver just like we have here in Minnesota,” the Democratic vice-presidential nominee said.
