Travel ban or no travel ban, the question is what citizen status did Obummer claim on his travel records? There must have been something those State Depart. records that Obummer needed to hide awfully bad, since there is one dead body in D.C. relating to the pilfering of State Department records. John Brennan reminds me a lot of Sandy Berger. Each, turned out to be “security advisers”??? and each pilfered official government records. One at the National Archives and the other at the State Department. It must go with the title.
Travel records? The only record of travel is the stamped passport, which the State Department does not have access to except when someone exits or returns to the US. For those countries requiring visas, you go to the country in question for a visa. The State Department keeps no records of one's travel outside the US.
The only information retained by the State Department are the passport applications. They could contain some very revealing information. The travel to Pakistan would not be included even if he used a US passport.
