Happy Valentine's Day to those who celebrate, or you can add Massacre if you don't.

Minnesota National Guard members have arrived at a federal building and were directed to distribute donuts, coffee, and hot chocolate to anti-ICE protesters. Guard members were issued reflective vests so they would not be mistaken for federal agents.
