“President William Jefferson Clinton wrote one EO that can cover all of these. He wrote Executive Order 12919 on June 3, 1994, which was released on June 6, 1994.
This EO will be the only thing he needs to enact in order to become a fully empowered dictator. It covers all of the EOs mentioned previously. The only thing this EO doesn’t do is define WHAT the “national emergency” would have to be in order for this EO to be signed. Please keep that in mind. Anything can be declared a “national emergency” to facilitate EO 12919 being enacted.”
