There is zero indication this had anything to do with the ban, he was not held detained , but his phone was. I think it's part of his job, and the verge is creating straw men
You and I have very different definitions of detained then. 40 minutes? So everyone around him was detained in detaining room, with sleeping cots, but he wasn't? Please explain that one?
And ITAR has fuck all to do with reentering the country.
Also, the time was longer than 40 minutes. He waited that long before talking with someone following detention. He then was forced to give up his phone/password and waited another 30 minutes while it was searched.
