How about Nixon after Agnew resigned but before Ford was approved by congress? Or Ford after Nixon resigned and Rockefeller (?) was approved? Then there’s LBJ after JFK was killed. Same for Lincoln’s and McKinley’s VPs.... I forget those guys.
Nope. This President served without a VP for his entire term.
Guess I’ll give a hint.
There was a successful assassination of a sitting President.
Not LBJ . . . maybe Andrew Johnson?
