Two Democratic senators are slamming the government’s secret interpretation of its surveillance powers under the USA PATRIOT Act. In a letter to Attorney General Eric Holder, Sen. Ron Wyden of Oregon and Sen. Mark Udall of Colorado said Americans would be “stunned” to learn what the government believes they can do under the law. The senators also questioned the value of the government’s secret efforts to national security. They write: “There is now a significant gap between what most Americans think the law allows and what the government secretly claims the law allows.”
