In recent history, the signing of the certification has become a ceremonial function attended by various dignitaries, which may include the President. President Johnson signed the certifications for the 24th and 25th Amendments as a witness, and President Nixon similarly witnessed the certification of the 26th Amendment along with three young scholars. On May 18, 1992, the Archivist performed the duties of the certifying official for the first time to recognize the ratification of the 27th Amendment, and the Director of the Federal Register signed the certification as a witness.
