From the American Constitution Society:
A constitutional amendment limiting presidential pardon power is being contemplated by Rep. Jerrold Nadler (D-N.Y.), TPM Muckraker reports. The congressman said during a public forum that he would introduce an amendment in the coming months to restrict the “president’s near absolute pardon power,” according to TPM.
Nadler has already, in a resolution, called on President George W. Bush to refrain from using his power to issue so-called “blanket pardons” of government officials involved in carrying out administration counterterrorism policies, especially those involved in torture of detainees in Afghanistan and Iraq and those involved in implementing the domestic spying program.
