36 CFR § 1270.20 - Presidential records in the physical custody of the Archivist.

During a President's term of office, the President may request that the Archivist maintain physical custody of Presidential records, including digital or electronic records. However, the President remains exclusively responsible for control and access to their records until their term of office concludes. During the President's terms of office, the Archivist does not disclose any of these records, except under the President's direction, until the President's term of office concludes. If a President serves consecutive terms, the Archivist does not disclose records without the President's direction until the end of the last term, or the end of another period if specified in 44 U.S.C. 2204 and subpart E of this part.
