That is false. There has been lots of prosecution of fraud in Minnesota including by Somalis. When a random YouTuber started accusing places without much evidence this blew up but didn't do anything to help actual investigations of corruptions. It did help Trump push his racist agenda and claim we need to deport Somalis because of actions of a handful of individuals. Which is nonsense not only when one compares it to the massive corruption from the Trump administration but when one realizes most Somalis Americans already have citizenship and a good deal are born in the US
