First, Canada has done a great deal on the security side since 9/11. I've got a long list of things that we've done here. We responded quickly and very well. Three months after 9/11, Parliament passed an omnibus terrorist bill. Not everybody agreed with it, but we were shown to be taking action. We did a lot of other things, but at the heart of the matter, the U.S. Congress thinks we haven't done enough. They see us as the weak link in North American security and they see it primarily because of our refugee and immigration policies. Hillary Clinton has said more than once that the 19 terrorists who blew up the World Trade Center came from Canada. CBS announced on the day of the bombing of the trade center that they came into Vermont from Quebec.
