The Rev. Jesse Jackson and a group of Occupy Atlanta protesters took over the lobby of SunTrust Plaza in downtown Atlanta for about an hour.
The group sang protest songs during the takeover Friday afternoon at the Atlanta-based bank's headquarters. Workers were let out of the building.
Adrian Harden of Jackson's Rainbow-PUSH coalition says the occupiers are protesting economic conditions and foreclosure rates across the country.
After the protest, Jackson said outside that the movement should be about banks and financial conditions and not about clashes with mayors and police.
Occupy Atlanta protesters camped in downtown Atlanta's Woodruff Park until they were ordered out last week by police.
