The conference, which is organized by the Trayvon Martin Foundation, is a three-day event that helps mothers who have “lost children or family members to senseless gun violence.”

Circle of Mothers was founded by Sybrina Fulton, whose 17-year-old son, Trayvon Martin, was fatally shot by neighborhood watch volunteer George Zimmerman in 2012.

Fulton is one of several mothers who lost their children to gun violence or in police custody, and then campaigned for Clinton during the Democratic presidential primary.

Those attending the Clinton speech are asked to donate $1,500, with the money raised going to the foundation.
