“If he [Obama] was traveling to countries to which Americans could not travel on a US passport in 1981 (Pakistan, possibly Iran), what passport was he using?”
In 1981, Obama (age 19), traveled to Pakistan with his Pakistani roommate from Occidental College in LA and stayed with his roommate’s family for 3 weeks.
Attorney Philip J. Berg who has a federal suit pending to require Obama to prove US citizenship already has proof from the Indonesian state department that Obama traveled on an Indonesian passport when he visited Pakistan in 1981.
