PROTESTS HAVE BEEN received from supporters of Congressman Fort and ex-Senator Frelinghuysen in respect to Senator Baird's reported statement. Several weeks ago a statement was made from the White House that the President has taken no part as between Republican candidates in New Jersey or in the primaries of any other State. That still holds good. This is also in accord with the expressed wish of each of the candidates.
Note: On June 14, 1930, Senator David Baird, Jr., issued a statement saying that Dwight W. Morrow, Ambassador to Mexico, was President Hoover's choice for Senator from New Jersey. The primary contest candidates for Senator were Ambassador Morrow, Congressman Franklin W. Fort, and ex-Senator Joseph S. Frelinghuysen.
