Credit Checks by the Government 'legal'

More privacy invasion by the Executive Branch:

Vice President Dick Cheney said Sunday the Pentagon and CIA are not violating people’s rights by examining the banking and credit records of hundreds of Americans and others suspected of terrorism or espionage in the United States.
Rep. Silvestre Reyes, D-Texas, the new chairman of the House Intelligence Committee, said his panel will be the judge of that.
National security letters permit the executive branch to seek records about people in terrorism and spy investigations without a judge’s approval or grand jury subpoena.
