With Tim Walz joining Democratic presidential candidate Kamala Harris on the campaign trail as her newly selected running mate, critics are blasting the Minnesota governor for what they claim was his failure to prevent a massive COVID-19 fraud scheme that has ensnared the state government. According to federal charges filed over the past couple of years, at least 70 people were part of a wide-ranging criminal conspiracy that exploited two federally-funded nutrition programs to fraudulently obtain more than $250 million in one of the largest COVID-era fraud schemes anywhere in the nation. The defendants allegedly used a Minnesota-based nonprofit organization called Feeding Our Future to avoid tough scrutiny from the Minnesota Department of Education, which was supposed to be conducting oversight of the programs.

On Tuesday, shortly after Walz was announced as Harris' running mate, the Minneapolis Star-Tribune newspaper published a story saying the case was one of the leading "vulnerabilities for Walz." By then, the pro-Trump group MAGA Inc. had already blasted out an email calling Walz "an incompetent liberal" for, among other things, "allow(ing) one of the largest fraud schemes to happen under his watch.
