A union watchdog is working to make Gov. and vice presidential candidate Tim Walz’s (D., Minn.) ties to teachers unions a liability before November’s election.

In an ad debuted with the Washington Reporter, the Public Labor Unions Accountability Committee (PLUAC) “demand[s] accountability” after the Democratic Party spotlighted union leaders such as Randi Weingarten, Becky Pringle, and Stacy Davis Gates at last week’s Democratic National Convention. “Harris and Walz: champions for their radical agenda,” it says. 

“Teachers’ unions have found their fighters,” the ad says. “Teachers’ unions shut kids out of schools, demanded police-free schools, and tried to ban charter schools, while sending their own children to private schools,” the ad mentions.
