Nothing about this in the report signed by Rep. McCaul March 2014, i.e one year after your ref.

Most of the info I have on this creep is my memories of the Boston Marathon bombing. I was researching the investigation as the situation developed.
He was a frequent guest at the White House before the bombing, FLOTUS visited him in the hospital, and all photos have either been photo shopped or scrubbed. He is an enemy of the United States - that is all I need to know.
He was arrested in Boston the day of the bombing, identified by a witness as having set off one of the bombs. That is why his hands were burned. Photos of his bandaged hands have now been photo shopped so no bandages appear.
As for “reliable sources”, as is typical of the NWO who control all news media, I guess you will have to rely on people like me who value liberty and truth.
