NEW: Gov. Tim Walz deflects blame as he addresses his state's massive fraud scandal: "We've got Republicans here in the state legislature playing hide and seek with potential whistleblowers." "We've got conspiracy theorists, right-wing YouTubers breaking into our daycares, demanding access to our children." "We've got the president of the United States demonizing our Somali neighbors and wrongfully confiscating funds that Minnesotans rely on." "Republicans are playing politics with the future of this state."
