After the election of Sen. Alejandro García Padilla as the 10th elected Governor of Puerto Rico on November 6, 2012, McClintock became the statutory chairman of Governor Fortuño's Outgoing Committee on Government Transition, the first and so far only to have chaired both the Incoming and Outgoing Committee on Transition since the approval of the Government Transition Law of 2004. On January 2, 2013, following long-standing tradition, he opened the Governor-elect's Inaugural Ceremony, minutes before completing this last stage of his public service career. Having served a full four-year term, McClintock tied with Secretary Fernando Chardón as the third longest-serving Secretary of State. Only Secretaries Sánchez-Vilella and Burgos served longer terms.
