evidence: Then president, Trump blistered the governor for the protests that consumed Minneapolis following George Floyd’s murder, and for not moving faster to deploy the National Guard. And though Walz’s state is not expected to be competitive this year, the handling of that crisis by Kamala Harris’ newly minted running mate is likely to be a focal point again now. [...] Trump has already laid the groundwork for a protest-based attack on Walz. He made the Minneapolis unrest a centerpiece of his 2020 campaign, casting the nation’s Democratic-run states and cities as lawless enterprises of the left. And this year is no different. At a recent rally in St. Cloud, Minnesota, the former president resurrected a four-year-old false claim that he sent the National Guard to respond to the civil unrest, following Floyd’s murder by a Minneapolis police officer, after Walz failed to do so. [...] Walz’s office has said that the governor activated the guard in response to requests from officials in Minneapolis and St. Paul.
