With Cheney's urging, he insisted that he had that right under the US Constitution, especially during wartime.
The presidential legacy of George W. Bush is perhaps best expressed in four words: He kept America safe.
Many legal scholars question President Bush's claim to unilateral power as commander in chief in the war on terror. And experts will long debate his aggressive approach to the fight against Al Qaeda – authorizing warrantless wiretaps within the US, secret kidnappings of terror suspects, coercive interrogation tactics, and military commissions with stripped-down legal protections.
But even Mr. Bush's harshest critics must concede that on his watch the country remained free of further terrorist atrocities following the 9/11 attacks.
The deeper question is at what price?
At the heart of the debate over Bush's legacy is a fundamental difference in outlook over what it means to remain faithful to the constitutional protections laid down by America's founding generation.
Critics say the Bush administration's expansive vision of executive power eclipsed the Constitution's mandated system of checks and balances. Some see the Bush years as lurching toward an imperial presidency, posing a direct threat to the essence of American liberty.
"The breadth of the theory that they were articulating is as broad as any theory of presidential power offered by any administration in history," says Gene Healy, a vice president at the Cato Institute in Washington and author of "The Cult of the Presidency: America's Dangerous Devotion to Executive Power."
