Shane [Trejo] later testified that he noticed that the city of Detroit Clerk’s Office and its emblem were written on the white van that showed up with the ballots. City Clerk Janice Winfrey‘s name was on the van and a number presumably for Janet Winfrey’s office.
“And by the way could anyone make out the signs on the trucks?”
Definitely not USPS.
Maybe a local delivery service or print shop?
