Lawmakers in the House and the Senate have reached an agreement that would renew key provisions of the Patriot Act, though amendments are still possible. One of the sections, known as the "lone wolf" provision, allows terrorist investigations of non-citizens without having to show connections to a terrorist organization. The Patriot Act expanded the authority of law enforcement and intelligence agencies to monitor private communications and access personal information. Among other things, the Patriot Act amended the Foreign Intelligence Surveillance Act (FISA) to allow the FBI to use National Security Letters for In place of court-approved warrants. In 2010, 24,287 NSLs were issued, up 64% from the previous year. For more Information, see EPIC: USA Patriot Act and EPIC: Foreign Intelligence Surveillance Act.
