“This is the same EO that’s been in place since 1994 and apparently amended several times since.”
These EOs have been around for decades. Nixon signed one back in either 1970 or 1972. It does no good, though, to mention that. Some people (not you) want their Chicken Little parade.
They may have been around for decades, but this president is an evil bastard communist dictator who is attempting rather successfully to neutralize the constitution and congress, and that changes everything.
