A small group gathered outside the Fulton County Jail on Tuesday night to support dozens of people arrested at Georgia's state Capitol on Tuesday morning and afternoon.
They gathered to encourage lawmakers to expand Medicaid under the Affordable Care Act.
Police arrested 41 demonstrators.
Members of the Moral Monday Coalition met Tuesday night at the Fulton County Jail.
Organizers said the majority of the people arrested early Tuesday were still in jail Tuesday night.
Moral Monday activist Timothy McDonald said, "It's growing, and we know that this is not an event. This is the movement, and it's going to take time."
Among those arrested was the Rev. Raphael Warnock of Ebenezer Baptist Church.
Warnock said he welcomed the arrest to show his support of Medicaid expansion.
