the following years. Legacy In a May 27, 1975, memo to then-Deputy National Security Advisor General Brent Scowcroft, Senior National Security Council Staff Member Les Janka wrote that "Much of the press has already come to the conclusion that the Rockefeller Commission on the CIA will produce a 'white wash.' He argued that the President should act on, and even exceed, any recommendations by the commission in order to restore in it the public's trust and thereby prevent "a thorough and possibly shattering restructuring of the CIA's charter and organization" by the Church Commission:We cannot tolerate a situation where the White House simply "studies" the recommendations of the Rockefeller Commission, lets charges of "white wash" build even further, and gives by default a mandate to Senator Church to come up with a "final solution" to the CIA problem. Most evidence of how the investigation was internally hindered was not accessed until the 1990s. According to a National Security Archive Report, "Much of the work of securing release of the records was done by the John F. Kennedy Assassinations Records Board in the 1990s, and the documents were located at the National Archives and Records Administration at College Park, Maryland; or at the Gerald R.

On July 18, 1975, over a month after the final report was released, The New York Times reported that unnamed staff sources within the Rockefeller Commission said that Sidney Gottlieb commanded the CIA's LSD experimentation program, was personally involved in the experiment that killed researcher Frank Olson, then destroyed the program's records in 1973. President Ford issued an executive order on intelligence agencies and operations which included a prohibition on assassinations. This was followed by President Carter with executive orders on intelligence in May 1977 and January 1978. These widened the scope of the assassination prohibition by expanding it to ban "political assassinations" on government employees to assassinations by anyone working for or on behalf of the United States. This ban was repeated verbatim in President Reagan’s 1981 E. O. 12333. The Reagan E.O. remains in force, with every subsequent president continuing the ban. Church Committee Main Article: Church Committee Under media pressure, Ford publicly turned over assassinations material to the Church Committee, which completed its report in October 1975.
