Question

Why did the National Security Agency wiretap domestic phone calls, and why was this action controversial in the global War on Terror?​

Answer 1

The National Security Agency’s Warrantless Wiretaps:
Legal Terrorist Surveillance or Illegal Domestic Spying?
In 2005, the press revealed that President George W. Bush had authorized government wiretaps without a court warrant of U.S. citizens suspected of terrorist links. A national debate arose over whether such electronic eavesdropping was legal terrorist surveillance or illegal domestic spying.
