On that occasion he had been a keynote speaker at an event organised by the Department of Homeland Security (DHS), alongside the FBI and Muslim organisations, to talk about tackling extremism and defeating terrorism.Link (Thanks, Lloyd!)
"I am deeply disappointed," he said.
"The abusive attitude I endured last November I forgot about and I forgave, but I really do believe that British ministers and parliamentarians should be afforded the same respect and dignity at USA airports that we would bestow upon our colleagues in the Senate and Congress.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
