Modern-day, Second American Civil War. A seceded Texas is pounding DC with bombs. The President wants to leave. The presidential helicopters aren't an option anymore so he arranges a ground convoy. Catch is, his Chief of Staff has secretly flipped against him; he calls the Texas surrender hotline (totally stole that idea from Ukraine IRL lol) and gives them information that the President is about to move. He gets a call back from a Texan Colonel operating nearby in Fredericksburg, and this Colonel is the guy who will eventually arrest the President after his troops swoop in with choppers and stop Air Force One on the tarmac. Thing is, the Chief of Staff is talking to the Colonel, and assuming the Colonel is smart, he'd be right to be skeptical of the Chief of Staff. How can I help the Chief of Staff come off as more genuine? Is there something he can say, or a way he can say a particular thing, that might work?
