2Semiquincentennial Congressional Time Capsule

This section would direct the Architect of the Capitol to create a congressional time capsule called the Semiquincentennial Congressional Time Capsule. The Office of the Speaker of the House of Representatives, the Office of the Minority Leader of the House of Representatives, the Office of the Majority Leader of the Senate, and the Office of the Minority Leader of the Senate would jointly decide what goes inside it. The contents would have to include a single joint letter from those four offices, plus any other item the four offices jointly agree to include. Any item placed in the Time Capsule would have to be made of a material with a low risk of degrading, such as metal or archival paper, and could not be made of any organic or inorganic material with a high risk of degrading. The Time Capsule itself could be no more than 50 inches wide, 32 inches deep, and 48 inches high. In deciding what to include, the four offices could consult with the Architect of the Capitol, the Secretary of the Smithsonian Institution, and any other federal entities they consider appropriate. The Architect of the Capitol would have to prepare the Time Capsule to be sealed and buried at the Capitol Visitor Center, at a location the Architect chooses, with the approval of the Committee on Rules and Administration of the Senate and the Committee on House Administration of the House of Representatives. The burial would have to happen on or before July 4, 2026, timed so that people attending it could also attend the burial of a separate time capsule in Independence Mall in Philadelphia, Pennsylvania, held under section 7(f)(1) of the United States Semiquincentennial Commission Act of 2016 (36 U.S.C. 101 note prec.). The Architect would also have to install a plaque giving information about the Time Capsule, with content the Architect chooses subject to approval from the same two committees. The Time Capsule would stay sealed until July 4, 2276. On that date, the Speaker of the House of Representatives and the Majority Leader of the Senate would present it to the 244th Congress, and that Congress would decide how to preserve or use what is inside.
