During the 2018 Brett Kavanaugh nomination to be a justice of the United States Supreme Court, Parker wrote a column advancing the theory that the alleged victim, Christine Blasey Ford, was mistaken in her identification of Brett Kavanaugh, and that there must be a Kavanaugh doppelgänger.[16] The doppelgänger theory[17] was denounced as ludicrous and madness by multiple other Washington Post columnists, such as Max Boot,[18] Eric Wemple,[19][20] Jennifer Rubin, E. J. Dionne, and Avi Selk.
