Semiquincentennial Congressional Time Capsule Act

This section mandates the Architect of the Capitol to create a time capsule, officially named the "Semiquincentennial Congressional Time Capsule," as a commemorative artifact for the 250th anniversary of the United States. This establishes the physical object and its core purpose.

This provision outlines that the contents of the time capsule will be jointly decided by the Speaker and Minority Leader of the House, and the Majority and Minority Leaders of the Senate. It also specifies that the contents must include materials related to the U.S. Semiquincentennial, significant legislative and institutional milestones of Congress, and a message from the current Congress to the future Congress that will open the capsule.

This section directs the Architect of the Capitol to prepare the time capsule for sealing and burial on the West Lawn of the Capitol by July 4, 2026. It also specifies that the capsule will remain sealed until July 4, 2276, at which point the Speaker of the House will present it to the 244th Congress, which will then decide how to preserve or use its contents. A plaque will be installed to provide information about the capsule.
