Republicans wasted no time tagging Minnesota Gov. Tim Walz with a less-than-flattering nickname.

“Tampon Tim” became the top trender Tuesday on X shortly after Vice President Kamala Harris announced Mr. Walz as her running mate, a reference to the bill he signed last year requiring schools to provide free menstrual products in all student restrooms in grades 4-12.

“There is no universe where a man who gives tampons to teenage boys is going to be next in line to be president. #TamponTim,” said Stephen Miller, America First Legal founder and a senior advisor to former President Donald Trump, on X.

Make America Great Again Inc., a pro-Trump super PAC, promptly posted an ad that began with a scene of a boys’ restroom.

“Tim Walz is a weird radical liberal,” said the ad. “What could be weirder than signing a bill requiring schools to stock tampons in boys’ bathrooms?”

Mr. Walz was also criticized for signing an executive order last year protecting access to gender-transition drugs and surgeries for minors, a reaction to red-state laws barring those under 18 from accessing sex-change hormones and procedures.

Trump campaign spokesperson Karoline Leavitt said the governor’s positions represent a “threat” to women.

“As a woman, I think there is no greater threat to our health than leaders who support gender-transition surgeries for young minors, who support putting tampons in men’s bathrooms in public schools,” Ms. Leavitt said on Fox News. “Those are radical policies that Tim Walz supports.”

Clapping back was Hillary Clinton, the former Democratic presidential candidate, who praised the Minnesota law.

“How nice of the Trump camp to help publicize Gov. Tim Walz’s compassionate and common-sense policy of providing free menstrual products to students in Minnesota public schools! Let’s do this everywhere,” said Ms. Clinton on X.

It turns out that 28 states and the District of Columbia provide free menstrual products to students at school,

“Kamala Harris and Democrats could not have picked a more extreme politician for vice president, and hopefully this nickname will help draw attention to that,” he said in an email.
