Dozens of black senior citizens were ordered off a bus taking them to vote this week in Georgia.

The Atlanta Journal-Constitution reported that the bus was preparing to leave a county-operated senior center when the center director told them to get off.

LaTosha Brown, co-founder of Black Voters Matter, the group that arranged for the bus to take the seniors to vote early, told the Journal-Constitution that a county clerk called the senior center to raise concerns about the bus.

Brown said that Black Voters Matter had secured permission from the senior center for the event.

“We knew it was an intimidation tactic,” Brown said. “It was really unnecessary. These are grown people.”
