A leader of the US congressional insurrection against the National Security Agency's bulk surveillance programs has accused his colleagues of withholding a key document from the House of Representatives before a critical surveillance vote.
Justin Amash, the Michigan Republican whose effort to defund the NSA's mass phone-records collection exposed deep congressional discomfort with domestic spying, said the House intelligence committee never allowed legislators outside the panel to see a 2011 document that described the surveillance in vague terms.
