My portfolio reads: leads to Don Corleone
from Jay-Z – Politics As Usual Lyrics on Rap Genius
Meaning
In Jay-Z’s police records, it notes that he is buddies with major mafia bosses, like the fictional “Don” Vito Corleone from The Godfather

It could have more to do with an imaginary financial portfolio of sorts, rather then police records. If his life were a portfolio, it would show it leads to the kind of success or gains Don Corleone enjoyed.
