Immigration Bill at the end of last year that had millions allotted for High-Tech, and High-Speed, Fentanyl Scanners at the places where the VAST majority of the drug enters the u.S....i.e. Official Ports of Entry...in Semi-Trailers, of which tens of thousands enter each and every day.
As President for 4 years, he should know the facts about Fentanyl trafficking...so the kill that bill, IMO makes him complicit in all the deaths you noted.
Just one more example...as if it were needed...of why we must never again put a Malignant Narcissist, like Donald Trump in any position of responsibility...and certainly not the Presidency...but then, you don't really care, as you've previously posted.
