KENOSHA, Wisconsin — Sen. J.D. Vance (R-OH) blasted Gov. Tim Walz (D-MN) and accused him of lying about how his children were conceived, saying that he has engaged in a pattern of misrepresentations.

Vance made the remarks Tuesday to reporters traveling with him on his campaign jet, dubbed Trump Force Two. Earlier in the day, Gwen Walz, the Minnesota governor’s wife, told CNN that she and her husband used intrauterine insemination, or IUI, to conceive, not in vitro fertilization.
