Moms United for Black Lives
Moms United for Black Lives (also known as Moms United, or MU4BL) is an activist group based in Portland, Oregon, with branches in other U.S. cities, including New York and San Diego. The group, founded in 2020, was a fixture at the George Floyd protests in Portland; they wore yellow shirts, helmets, goggles, and gas masks, and they lead hundreds of people in chants as they marched to the Mark O. Hatfield federal courthouse.
