Could this have to do with the Saudi man who is being held in connection with the Boston terror bombings? "Kerry meeting with Saudi Foreign Minister abruptly closed," by Josh Gerstein for Politico, April 16:
A meeting Secretary of State John Kerry was to hold with Saudi Arabian Foreign Minister Saud Al-Faisal was abruptly closed to press coverage Tuesday morning.
The State Department provided no reason for the change, which was announced just 15 minutes before the scheduled 10 A.M. session, but media reports have said that a Saudi national in the U.S. on a student visa is a "person of interest" to investigators probing the bombings at the Boston Marathon on Monday.
The person being investigated was badly injured in the attack, sources said.
"Apologies for short notice," the State Department's press office told reporters as it announced the change. A spokesperson did not immediately respond to a query about the closure of the meeting, which had been scheduled to include a so-called "camera spray" at the top of the session.
