Trump has mentioned the USPS, the Dems wanted something like an $8 billion bailout added and he said No, and more than just No, can’t remember. Plus the USPS has been invovled in election fraud crap. Needs to be pared way, way down and huge pension reform as well.
I think he will deal with it via some good hard hitter as you note.
The USPS is also subsidizing Amazon. They lose money on every Amazon package. Trump told them to raise rates and make other changes necessary.
