Leavitt, 27, currently a spokesperson for Trump's transition, would be the youngest White House press secretary in history. Previously that distinction went to Ronald Ziegler, who was 29 when he took the position in 1969 in Richard Nixon's administration.

Trump is expected to make Matt Gaetz his attorney general and Marco Rubio his secretary of state, and place Tulsi Gabbard, Kristi Noem and Stephen Miller in key posts.
