Transcripts from the Iran-Contra Hearings in 1987 record the following dialogue between Congressman Jack Brooks, Oliver North's attorney Brendan Sullivan and Senator Daniel Inouye, the Democratic Chair of the joint Senate-House Committee:
[Congressman Jack] Brooks: Colonel North, in your work at the N.S.C. were you not assigned, at one time, to work on plans for the continuity of government in the event of a major disaster?
Brendan Sullivan [North's counsel, agitatedly]: Mr. Chairman?
[Senator Daniel] Inouye: I believe that question touches upon a highly sensitive and classified area so may I request that you not touch upon that?
Brooks: I was particularly concerned, Mr. Chairman, because I read in Miami papers, and several others, that there had been a plan developed, by that same agency, a contingency plan in the event of emergency, that would suspend the American constitution. And I was deeply concerned about it and wondered if that was an area in which he had worked. I believe that it was and I wanted to get his confirmation.
Inouye: May I most respectfully request that that matter not be touched upon at this stage. If we wish to get into this, I'm certain arrangements can be made for an executive session.
Exercises similar to Rex 84 have happened in the past. For example, from 1967 to 1971, the FBI kept a list of over 100,000 persons to be rounded up as subversive, dubbed the "ADEX" list.
REX８４とはReadiness Exercise 1984のこと
米国でマーシャルロー発動時に憲法を停止させることも出来ることでlieutenant Coloneel（中佐）のOliver Northの発案によるもの。FEMA発動の際に彼がFEMA大統領になることは規定の路線でもあろうか。
