Congressional leaders had sought to extend the key national intelligence tool for five years.

However, members from both sides of the aisle thwarted that plan as they sought more stringent privacy protections for U.S.

citizens.

the new April 30th deadline.

The tool is Section 702 of the Foreign Intelligence Surveillance Act, which allows targeted warrantless surveillance.

The government says the intelligence collected underpins a huge share of the president's daily intelligence briefings.

But critics, both Democratic and Republican, have long been concerned about the government reviewing Americans' private information gathered as part of the surveillances.
