The President's News Conference
THE PRESIDENT. I have only one announcement, that is the appointment of Mr. [Charles B.] Rugg of Massachusetts as Assistant Attorney General. He is a son of the present chief justice of Massachusetts. Other than that I have nothing.
Note: President Hoover's eighty-seventh news conference was held in the State, War, and Navy Building at 4 p.m. on Friday, January 31, 1930.
