FFS that's not what Tim Walz did, at all. He signed (as opposed to vetoing) a bipartisan bill to provide free menstrual products to students, after a years-long campaign by students who had to pay for these at school.

The law doesn't say anything about boys bathrooms or genders. At most it can be argued that by not specifying that only girls bathrooms are included, it avoids singling out female-to-male and intersex students who use boys bathrooms for persecution. Which is of course controversial to Republicans.
