It means the man who will be the oldest president in history at his January inauguration will have the youngest press secretary in history.

President-elect Donald Trump reached into his inner circle on Friday and chose his transition spokesperson, Karoline Leavitt, as his White House press secretary, putting a 27-year-old firebrand in position to aggressively defend him. Leavitt has endeared herself to Trump by her ardent defense of him in news interviews and her take-no-prisoners style, Trump advisers said. The job of the White House press secretary typically is to help inform the American people about presidential activities without betraying the confidence of the boss.
