Officials have expressed caution around the nationwide “No Kings” protests after two Minnesota state lawmakers and their spouses were shot early Saturday. One lawmaker and her husband died while the other two survived with severe injuries.

Additional security measures have been taken at events, caution has been advised, and Minnesota has canceled their protest events entirely as the shooter remains on the loose. The shooter had a manifesto with a list of several prominent Minnesota lawmakers, including Gov. Tim Walz (D-MN), and had a “No Kings” flier.
