Contents Secret as Reagan Offers Reply in Iran-Contra Probe

President Reagan has submitted written answers to questions submitted in the Iran-Contra investigation by independent counsel Lawrence Walsh, the White House said today.

While confirming that the replies had been delivered, White House spokesman Marlin Fitzwater refused to discuss the material, saying it is all covered by grand jury secrecy rules.

He said Reagan’s statements amounted to sworn testimony.

Walsh is investigating the role of former White House aides Oliver L. North and John M. Poindexter and others in the diversion of profits from the Iran arms sales to the Contra rebels in Nicaragua.

North has told Congress that he assumed Poindexter, his boss, had told Reagan about the diversion. Poindexter said he did not inform Reagan but assumed the President would have approved if he had been informed.
