Two US senators on the intelligence committee said [that] thousands of annual violations by the National Security Agency on its own restrictions were the tip of the iceberg." "The executive branch has now confirmed that the rules, regulations and court-imposed standards for protecting the privacy of Americans' have been violated thousands of times each year," said senators Ron Wyden and Mark Udall, two leading critics of bulk surveillance, who responded [to] a Washington Post story based on documents provided by whistleblower Edward Snowden. "We have previously said that the violations of these laws and rules were more serious than had been acknowledged, and we believe Americans should know that this confirmation is just the tip of a larger iceberg." On July 31, Wyden, backed by Udall, vaguely warned other senators in a floor speech that the NSA and the director of national intelligence were substantively misleading legislators by describing improperly collected data as a matter of innocent and anodyne human or technical errors. In keeping with their typically cautious pattern when discussing classified information, Wyden and Udall did not provide details about their claimed "iceberg" of surveillance malfeasance. But they hinted that the public still lacks an adequate understanding of the NSA's powers to collect data on Americans under its controversial interpretation of the Patriot Act. "We believe the public deserves to know more about the violations of the secret court orders that have authorized the bulk collection of Americans' phone and email records under the Patriot Act," [they] said.
