This is the relevant section from Blair’s written statement (MHO)
http://intelligence.senate.gov/090122/blair.pdf The second part of building trust is to carry out the mission of the Intelligence Community in a manner consistent with our Nation’s values, consistent with our Constitution and consistent with the rule of law.
The intelligence agencies of the United States must respect the privacy and civil liberties of the American people, and they must adhere to the rule of law. Lawful Surveillance, Lawful Detention and Interrogation
In a dangerous world, government agencies need authority to collect intelligence on terrorists before they strike, in order to protect the American people. But in a free society, that authority cannot be unlimited. It must be exercised pursuant to law. I do not and will not support any surveillance activities that circumvent established processes for their lawful authorization. I believe in the importance of review and regulation of the use of those surveillance authorities. I believe in the importance of independent monitoring, including by the Congress, to prevent abuses and protect civil liberties.
