The White House is working to convince Congress that NSA surveillance programs are needed in the war on terror.
President Obama will meet with lawmakers from both parties at the White House Thursday to try to convince them that surveillance of phone and internet activity keeps Americans safe.
Colorado Senator Mark Udall will be among those at the meeting.
"I think knowing when I call somebody, from when I call somebody, and for how long I call somebody is a violation of your privacy," said Udall.
Congress is holding hearings to look into the programs. Some Senators questions how effective the information is in stopping terror attacks.
The NSA insists the surveillance programs are critical to national security, and are going public with details about them. On Wednesday the intelligence agency declassified three documents detailing the rules for collecting and analyzing phone records.
NSA director, General Keith Alexander, says the surveillance has helped foil 54 terror plots around the world, including the arrest of one suspect who was days away from attacking New York City subways with backpack bombs.
