Thank you for contacting the National Museum of African American History and Culture. We recognize and apologize for the frustration you have experienced. The museum is working through a backlog of group requests and has temporarily suspended the group reservation system until the backlog is successfully addressed. Be assured that the staff of the Museum is working as quickly and diligently as possible to address your constituents’ requests to visit the Museum.
On the museum's website there is a section for groups. You may want to check there.
