WATCH: Group of Karens form human shield to protect their Antifa kids from police

The mothers were apart of a larger crowd of roughly 400 people. One mom told BuzzFeed News that their mission was to protest the right for peaceful protests by citizens, which manifested in the so-called "Wall of Moms."

The Facebook event for the Wall of Moms says their goal was to protect protestors "without the use of violence."

"We moms are often underestimated. But we’re stronger than we’re given credit for. So what do you say, will you stand with me? Will you help me create a wall of moms?"

Barnum has since created a permanent Facebook group to organize more events. On Sunday, they will be joining demonstrations again, wearing yellow and handing out sunflowers.

Moms were asked to wear white to stand out from the crowd.
