As the U.S. Senate prepares to take up the Cybersecurity Information Sharing (“CISA”) Act, S. 754, open government organizations, privacy and civil liberties defenders, security experts, and tech companies are mobilizing to voice opposition to the bill. OpenTheGovernment.org is particularly concerned with the harm the bill would do to the Freedom of Information Act and transparency more generally. Open government organizations sent letters to Congress in June, and in March of this year, calling on the Senate to oppose the bill. CISA would add a new exemption to the Freedom of Information Act for the first time since 1967. Section 10 of the bill provides that any and all “information shared with or provided to the Federal Government pursuant to the Cybersecurity Information Sharing Act of 2015” is exempt from disclosure under FOIA—even if it is private information unrelated to a cybersecurity threat.
