Semiquincentennial Congressional Time Capsule Act

This legislation mandates the creation of the "Semiquincentennial Congressional Time Capsule" by the Architect of the Capitol to commemorate the 250th anniversary of the United States. The capsule will be prepared for sealing and burial on the West Lawn of the Capitol by July 4, 2026 , with a commemorative plaque. The contents of the Time Capsule will be jointly determined by the Speaker and Minority Leaders of both the House and Senate. These contents must include materials related to the United States Semiquincentennial, important legislative milestones, and a message from Congress to the future Congress. The Time Capsule is designated to remain sealed for 250 years, until July 4, 2276 . On that date, the Speaker of the House of Representatives will present the capsule to the 244th Congress, which will then decide how its contents should be preserved or utilized.
