Congressional Staffers Get Info on Secret Yahoo Order

Obama administration officials briefed key congressional staffers about a secret court order to Yahoo that prompted it to search all users’ incoming emails for a still undisclosed digital signature, but they remain reluctant to discuss the unusual case with a broader audience. Executive branch officials spoke to staff for members of the Senate and House of Representatives committees overseeing intelligence operations and the judiciary, according to people briefed on the events, which followed Reuters’ disclosure of the massive search.
