The full article written by James Macload of 'The Telegram' can be found here but here's what was said regarding 9/11:
“We’re spreading awareness about the impossibilities or inaccuracies and cover-ups since Sept. 11, 2001,” Harris said. “That’s a main issue that we’re focusing on in that aspect of our company.”
It wasn't much, but it was something... especially when you combine that little piece with the fact that one of the lead characters in the show wore an 'Investigate 9/11' T-Shirt exposing a couple of hundred people over the course of a few days to this important cause.
One step at a time right?
