Minnesota Gov. Tim Walz (D) on Thursday activated the state’s National Guard to respond to the upheaval over the death of 46-year-old George Floyd in police custody, as federal and local officials said they continue to investigate, according to the Washington Post.

The crisis bears more than a passing resemblance to Governor Richard Hughes’ deployment of the National Guard to Newark in 1967, in the aftermath of stuggles following the police beating of cab driver John William Smith.
