Watergate Impeachment Hearings House Judiciary Committee, July 29, 1974. Delbert Latta (R Ohio) Let me just complete my comments concerning the national security. The threat was compounded by the fact that Mr. Ellsberg was a former staff member of the National Security Council itself and the prospects that he might divulge additional information, and the realization that the Soviet Government had already received a copy of the Pentagon Papers on June the 17th and might be the recipient of additional classified information. He also had had a broad area of access to the clearance to see classified information including SIOP, better known as the Nation's Single Integrated Operations Plan. Now what does this encompass? Nothing other than all, and I stress the word all, of this Nation's military contingency plans in case of war, including integrated conventional and nuclear options. That is what concerned the President. Peter Rodino (D New Jersey). The time of the gentleman has expired.
