The F.B.I. conspired to leak a manifesto by Khalid Shaikh Mohammed to The Huffington Post. It came to light last week that agents had approached a member of the defense team for a detainee facing trial before a military commission over the Sept. 11 terrorist attacks. He was asked to sign a confidentiality agreement.  http://www.nytimes.com/2014/04/22/us/politics/official-denies-fbi-was-investigating-manifesto-leak.html?ref=us  The disclosure derailed a week of pretrial hearings, and the special trial counsel, Fernando Campoamor-Sanchez, an assistant United States attorney, is leading an investigation into the matter. It was widely speculated that the subject of an F.B.I. inquiry was how the 36-page manuscript by Mr. Mohammed — the self-described architect of the attacks — had been leaked. But in a public court filing on Monday, Mr. Campoamor-Sanchez said that was not true. He did not identify the investigation’s actual subject, although he apparently offered greater details to the judge in an accompanying classified filing.
