Harry S. Truman did not ride a subway to work while president. DC most certainly had no subway then. In fact, as president he had no need to ride to work. He lived in the White House and in the Blair House across the street while the WH was undergoing extensive renovations.
HST’s SS protection detail was much smaller than JFK’s.
When Puerto Rican terrorists attempted to assassinate him at the Blair House HST was so pissed off he had to be held back from attacking the wounded perps. Stephen Hunter has a very good book about it.
Lol. I don’t know where that notion came from. I have to be confusing stories I heard years ago. I need to eat more blueberries.
