While a guest on MSNBC's Morning Joe on the 13th anniversary of 9/11 on 11 September 2014, Chris Matthews gave diatribe against Dick Cheney, suggesting he caused 9/11:
CHRIS MATTHEWS: We're not even sure of this yet, the connection between what we did back in Saudi Arabia in 1990, putting all those tens of thousands of troops into the holy land of Mecca and all that, and what that really did to stimulate or trigger or justify in the hearts of the suicide bombers of 9/11.
What role did that play? And we had no idea that would do that. And of course, the decisions we made in Iraq about getting rid of the Sunnis and the government and de-Baathicizing [sic] and sending those people off to join ISIS.
