I didn’t say that because I know it is not true. He could have gone there, if he had been able to obtain a visa, with a US passport; if he had had one. But he didn’t have a US passport until he became a senator, I think an Illinois senator. So, since he didn’t have a US passport, it must have been from another country; they wouldn’t have let him in to Pakistan and Indonesia - and IIRC he may have visited Hyderabad, India - without a passport of some kind or another.
Do we know that the passport he got as an Illinois senator was his original issue?
That's important, if it's true.
Yes, obviously he needed a passport to go to Pakistan in 1981.
