Trump did not blame Bush. He was answering the claim that Bush kept America safe in his 8 years. He said that 9-11 happened on Bush's watch, not that Bush caused it or ineptly allowed it.

9-11 did, indeed, happen on Bush's watch. Bush did not keep America safe though he made America safer after 9-11.
It seems as if the bushies are trying to imply that 9-11 did not happen in GW's term

Incidentally those 9-11ers got their pilots' licenses in Florida on another Bush's gubernatorial watch.
