So someone else could raise the "Obama is a muslim" issue and put it on the table for discussion with Trump still being able to maintain the position that "I didn't bring it up". Trump gets an issue that favors him in the talking points, gets to be portrayed as the real victim in all this ("why should I be expected to fight Obama's battles for him") and gets to have the Dems painted with the Pro-Terrorist tag all at the same time. Why wouldn't Trump have planted that guy if he had thought idea up?
At this point in Obama’s last term (hopefully), I don’t see why Trump would want to bring this up. I think he was a plant but not by Trump.
