Former president Donald Trump has endorsed the primary opponent for Assembly Speaker Robin Vos, R-Rochester, taking his long-running public feud with the powerful Wisconsin Republican to a new level. In a statement released Tuesday, Trump pledged his "Complete and Total Endorsement" of Adam Steen, accusing Vos of being a RINO, which stands for "Republican In Name Only." "Although Vos claims to be a Republican, he is constantly fighting America First efforts and policies," Trump said in the statement. "Our great slogan, Make America Great Again, is not exactly high on his list!" Trump has frequently criticized Vos for not doing more to overturn the results of the 2020 presidential election in Wisconsin, a step election law experts say would be unconstitutional and impossible.
