The secret legal opinions issued by Bush administration lawyers after the Sept. 11 attacks included assertions that the president could use the nation’s military within the United States to combat terrorism suspects and to conduct raids without obtaining search warrants.

The opinions reflected a broad interpretation of presidential authority, asserting as well that the president could unilaterally abrogate foreign treaties, ignore any guidance from Congress in dealing with detainees suspected of terrorism, and conduct a program of domestic eavesdropping without warrants.

But taken together, the opinions disclosed Monday were the clearest illustration to date of the broad definition of presidential power approved by government lawyers in the months after the Sept. 11 attacks.

The author of many of the memoranda was, of course, John Yoo, who also opined that “First Amendment speech and press rights may also be subordinated to the overriding need to wage war successfully” and that “the current campaign against terrorism may require even broader exercises of federal power domestically.”
