The Justice Department on Monday declined to answer requests by House Intelligence Committee Chairman Devin Nunes, R-Calif., for more information about the reported use of FBI informants while investigating President Trump's 2016 campaign. Nunes had given Deputy Attorney General Rod Rosenstein until 5 p.m. ET to say whether the FBI had used "informants against members or associates of the Trump campaign and if so, how many informants were used and how much money was spent on their activities?" In his response to Nunes, Assistant Attorney General Stephen Boyd said: "Many of your requests relate to documents and information regarding issues surrounding confidential human sources that are solely in the custody and control of the FBI." "The FBI retains and has the ability to produce the documents requested in a manner consistent with its obligation to protect confidential human sources and methods," Boyd added. FBI says it produced majority of documents to Congress; chief intelligence correspondent Catherine Herridge reports from Washington.
