inspectors do not have any separate agreement on visiting the military site. iran will provide soil samples and other installations. the u.n. inspectors will not independently get them themselves. let me tell you the worst thing. what you guys agreed to was, we can t take samples there. they re going to be able to test by themselves. even the nfl wouldn t go along with this. how in the world can you have a nation like iran doing their own testing? reporter: secretary kerry says the soil sample issue is classified. when senators say the nfl drug testing program is stricter than the iranian agreement, the secretary of state considers going wind surfing again, he will face choppy waters on capitol hill. thanks very much.
