WHY at 4:30 AM???? WEIRD or she’s a BAT!
Her hero is Vlad, and I don’t mean Putin
I believe the goal was to stage a 'look at this half empty truck leaving the distribution center, why is Dejoy delaying the mail?' photo shoot. Trucks start rolling from P&DCs at 1am to make it to the stations in time, ideally the late truck would make the most dramatic photo opportunity since it'd be mostly empty since it brings back the equipment the clerks sorted out of at the station.
“WHY at 4:30 AM???? “
I suspect the middle of the night would be the time when they have the most amount of “undelivered mail”.
