The officer carries the encrypted comm devices— the football- with the military’s codes (just like a guard— “halt who goes there?” “password?” ) to verify a go command from the CIC. (like “FailSafe”) The Executive’s secretary keeps his “cards”— and this became the Holy Writ standard practice, after that moron Billie Boy Clinton— freaking LOST his!! Imagine how vulnerable millions were because of that powder monkey with tertiary syphilis. So, that is why the Pres’ personal secretary maintains them close by.
Thanx for the info.
