President Donald J. Trump announced a National Gathering of Prayer to be held on the National Mall in Washington, D.C., on May 17, 2026. He invited Americans nationwide to “come to the National Mall and pray,” saying the event will “re-dedicate America as one nation under God.” Trump framed the gathering as a reaffirmation of the country’s Christian heritage, declaring “America is a Christian nation.” Organizers say the rally aims to unite faith communities and supporters for collective prayer and patriotic ceremony; critics warn about church-state separation concerns. Attendance, security plans, and endorsements were not detailed in the announcement publicly.
