A mainstream media figure is openly questioning the official 9/11 story, a sign of how far conspiracy talk has moved into the political center.

• The claim: a group of Israelis were arrested that day after being seen celebrating the attacks, suggesting they knew in advance.
• The bigger insinuation is that American or Israeli officials may have helped or let it happen.
• The collapse of World Trade Center Building 7 is held up as the part of the story that still does not add up.
• The attacks on people who ask these questions are framed as proof there is something to hide.

Outlook: Expect more pushback over 9/11 revisionism and US-Israel ties in right-wing media.
