You generally expect leaders of countries to be well-traveled, right? Well, a diplomatic trip to Iran in 2014 taken by Norway’s former prime minister, Kjell Magne Bondevik, caused him to be detained for about an hour at Dulles Airport in Washington, D.C. on Tuesday.

Bondevik was traveling to the U.S. to take part in the National Prayer Breakfast, where, according to the Washington Post,

“[H]e was detained and questioned for about an hour, all because of a passport stamp. His passport — which clearly stated he is the former prime minister of Norway — indicated he had taken a 2014 trip to Iran, where Bondevik said he had attended a human rights conference.”

Talking about the incident, Bondevik said, “I was surprised, and I was provoked. What will the reputation of the U.S. be if this happens not only to me, but also to other international leaders?”
