Kevin Larson, a 68-year-old Canadian retiree with no criminal record, was stopped at the Blue Water Bridge on October 18, 2025, while attempting to enter Michigan to attend a No Kings protest against Trump's policies. After three hours of questioning, fingerprinting, a phone search, and a DNA cheek swab collected under threat of jail time, Larson was denied entry and returned to Canada. Border agents told him he was turned away due to the nature of his planned protest activity.
