yesterday, the U.S. Treasury closed a mail facility near its main building in downtown Washington after a suspicious letter was found bearing a Trenton, N.J., postmark...I wonder when the suspicious letter was postmarked.

Article above says the building's landlord had noticed FBI staking out the mail drop box nearby in "previous two days."

Letter received yesterday(?) in D.C. = letter posted from that drop box three days ago, possibly?

I'm not sure. I wonder if mail to the Treasury might have been delayed by the closing of the Brentwood facility.
