Second gentleman Doug Emhoff campaigned at the 7th annual Hmong Wausau Festival in Wausa, Wisconsin, on Saturday with Gov. Tony Evers and Sen. Tammy Baldwin.

Emhoff addressed Sen. JD Vance’s "cat lady" comments that he's been getting considerable criticism over, and called former President Donald Trump remarks “weird.”

"Over the last decade, she's not just been an amazing partner to me, but a loving parent to two kids named Paul and Ella," Emhoff said about his wife. "From day one, she's been present, nurturing and fiercely protected with them."

Vance responded to the criticism of his comments Friday during the "Megyn Kelly Show" podcast and claimed the comments made in a 2021 Fox News interview were taken out of context.

"This is about criticizing the Democratic Party for becoming anti-family and anti-child," Vance said.
