Dear Chairmen Roberts and Hoekstra. Vice Chairman Rockefeller, and Ranking Member Harman:
As you know, in responsc to unauthorized disclosures in the media, the President has
described certain activitics of the National Security Agency ("NSA") that he has authorized since
shortly after Septcmber 1 1,200 1 . As described by the President, the NSA intercepts certain
international communications into and out of the United States of people linked to al Qaeda or an
affiliated terrorist organization. The purpose of these intercepts is to establish an early warning
system to detect and prcvent another catastrophic terrorist attack on the IJnited States. The
President has made clear that he will use his constitutional and statutory authorities to protect the
Amer~can people from further terrorist attacks, and the NSA activities the President described are
part of that effort. Leaders of the Congress were briefed on these activities more than a dozen
tlnies.
The purpose of this letter is to provide an additional brief summary of the legal authority
supporting the NSA activities described by the President.
The NSA activities described by the President are also consistent with the Fourth
Amendment and the protection of civil liberties. The Fourth Amendment's "central requirement is
one of reasonableness." Illinois v. McArthur, 53 1 U.S. 326,330 (2001) (internal quotation marks
omitted). For searches conducted in the course of ordinary criminal law enforcement,
reasonableness generally requires securing a warrant. See Bd. ofEduc, v. Earls, 536 U.S. 822, 828
(2002). Outside the ordinary criminal law enforcement context, however, the Supreme Court has,
at times, dispensed with the warrant, instead adjudging the reasonableness of a search under the
totality of the circumstances. See United States v. Knights, 534 U.S. 112, 118 (2001). In
particular, the Supreme Court has long recognized that "special needs, beyond the normal need for
law enforcement," can justify departure from the usual warrant requirement. Vernonia School Dis!.
47J v. Acton, 5 15 U.S. 646, 653 (1995); see also Ci@ ofIndianapolis v. Edmot~d, 531 U.S. 32.41-
42 (2000) (striking down checkpoint where "primary purpose was to detect evidence of ordinary
criminal wrongdoing").
As explained above. the President determined that it was necessary following September 1 1
to create an early warning detection system. FISA could not have provided the speed and agility
required for the early warning detection system. In addition, any legislative change, other than the
AUMF, that the President might have sought specifically to create such an early warning system
would have been public and would have tipped off our enemies concerning our intelligence
limitations and capabilities. Nevertheless, I want to stress that the United States makes full use of
FISA to address the terrorist threat, and FISA has proven to be a very important tool, especially in
longer-term investigations. In addition, the United States is constantly assessing all available legal
options, taking full advantage of any developments in the law.
We hope this information is helpful
Sincerely,
William E. Moschella
Assistant Attorney General
