This bill establishes the Philadelphia Campaign Two Hundred and Fiftieth Commemoration Commission to organize and recommend federal activities for the 250th anniversary of the Philadelphia Campaign of the American Revolution. The campaign, which occurred in 1777-1778 across Pennsylvania, New Jersey, Maryland, and Delaware, was pivotal in convincing France to ally with the American cause and in professionalizing the Continental Army. The Commission's primary duty is to submit a report to Congress outlining recommended activities for the Federal Government to observe the anniversary. These recommendations may include acquiring and preserving artifacts, sponsoring interactive digital resources, organizing conferences and exhibitions, and developing nationally accessible educational materials. The Commission is also tasked with coordinating efforts among various State, local, international, and private sector entities involved in commemoration. Composed of 14 voting members , including the Librarian of Congress, the Chief Operating Officer of the Museum of the American Revolution, and 12 qualified citizens appointed by the President and congressional leaders, the Commission will operate without pay, though travel expenses are covered. The President of the United States will serve as an honorary, non-voting member and may invite the President of France and the Prime Minister of the United Kingdom to join. The Commission is authorized to hold hearings, procure services, accept donations, and appoint a Director and staff. It must submit interim reports to Congress and a final report by September 30, 2028 , detailing its activities and recommendations. The bill authorizes appropriations of $2,500,000 for fiscal year 2027 and another $2,500,000 for fiscal year 2028 to fund its operations, with the Commission terminating 120 days after its final report.
