G.O.P. SENATOR SAYS CONGRESS DESIRES DEEPER ARMS CUTS
''A majority of the Congress are looking for larger cuts'' in planned military spending than those announced last night by the White House, Senator Pete V. Domenici, the Republican chairman of the Senate Budget Committee, said today. But as President Reagan arrived late today at the White House from a weekend at Camp David, he defended his proposal to cut only a relatively small amount from the Defense Department budget. He told reporters, ''We've been cutting a budget that has been overgrown and extravagant over the years while in the same years, Defense has been a poor relative.'' The White House announcement last night brought to an end several weeks of intense maneuvering between Defense Secretary Caspar W. Weinberger and David A. Stockman, director of the Office of Management and Budget. It said that President Reagan had decided on cuts of $13 billion in projected military spending i n the fiscal years 1982-84 , as against the cuts of $20 billion to $30 billion sought by Mr. Stockman and senior White House aides. The fiscal year 1982 starts O ct. 1.
