Dear Mr. Clapper:

The undersigned civil society groups write to express our concerns about recent reports of an order issued under the Foreign Intelligence Surveillance Act (FISA) that compelled Yahoo! to scan the emails of all of its users, in real time, for a “signature” associated with a foreign power. We believe such a massive scan of the emails of millions of people, particularly if it involves the scanning of email content, could violate FISA, the Fourth Amendment, and international human rights law, and has grave implications for privacy.

According to reports, the order was issued under Title I of FISA, which requires the government to demonstrate probable cause that its target is a foreign power or an agent of a foreign power (such as a spy or a terrorist), and probable cause that the “facility” at which the surveillance is conducted will carry the target’s communications. If reports are true, this authority to conduct a particularized search has apparently been secretly construed to authorize a mass scan. Observing the press reports, Senator Wyden warned, as he did prior to the Snowden disclosures, that the government has secretly interpreted the law to permit surveillance that would surprise and concern the public.

We call on you to:

These disclosures can and should be made without compromising sources and methods of surveillance, and many are consistent with the types of disclosures called for in the USA FREEDOM Act.

We would welcome the opportunity to meet with you to discuss these matters further.

Sincerely,
