Mike Kehoe's order triggers a state of emergency due to civil unrest, even as no evidence existed of riots or other widespread violence in Missouri.

Missouri has joined Texas in preemptively activating the state's National Guard ahead of the "No Kings" protests planned at about 2,000 sites across the nation on June 14 against President Donald Trump.

The “No Kings Day of Defiance” was organized nationwide at the same time a military parade will mark the U.S. Army’s 250th anniversary in Washington, D.C. The date also coincides with President Donald Trump’s 79th birthday as well as Flag Day.
