Since being named U.S. Health and Human Services Secretary earlier this year, Robert F. Kennedy Jr. has targeted vaccine policy, and in May withdrew a federal recommendation for COVID shots for pregnant women and healthy children. Kennedy toured the site on Monday and said no one should face violence while working to protect the health of others.

The alleged gunman died of a self-inflicted gunshot, the Georgia Bureau of Investigation said, according to WSB. Patrick Joseph White, 30, had letters that showed his “discontent” with COVID-19 vaccines.
