John McCain blames AZ wildfires on undocumented immigrants

Here is another one from the “Pulled it out of my ass” file. John McCain says undocumented immigrants are to blame for the devastating wildfires in Arizona, saying,

There is substantial evidence that some of these fires are caused by people who have crossed our border illegally. They have set fires because they signal others, they have set fires to keep warm, and they have set fires in order to divert law enforcement agents and agencies from them. The answer to that part of the problem is to get a secure border.

Of course the Senator failed to offer any evidence.
