Not saying he didn't lie but I do believe a senior senator could access Arlington after hours without too much trouble.
Not without a lot of people jumping through hoops. The President yes. A Senator...no.
Trust me...it takes a LOT of planning and prior notification for one of these "unplanned" visits.
I'm going to call my friend that runs the ANC public affairs office in the morning to find out for sure.
But I've worked in and around ANC for long enough to have this set off my stink meter big time.
