At a Congressional hearing this morning that veered into contentious arguments and cringe-worthy moments, the Department of Homeland Security (DHS) spilled the beans on their social media monitoring project.

DHS Chief Privacy Office Mary Ellen Callahan and Director of Operations Coordination and Planning Richard Chavez appeared to be deliberately stonewalling Congress on the depth, ubiquity, goals, and technical capabilities of the agency’s social media surveillance. At other times, they appeared to be themselves unsure about their own project’s ultimate goals and uses. But one thing is for sure: If you’re the first person to tweet about a news story, or if you’re a community activist who makes public Facebook posts–DHS will have your personal information.

The hearing, which was held by the Subcommittee on Counterintelligence and Intelligence headed by Rep. Patrick Meehan (R-PA), was highly unusual. Hacktivist collective Anonymous (or at least the @AnonyOps Twitter feed) sent a sympathizer to the visitor gallery to liveblog the proceedings under the #spyback hashtag.

Interactions between the DHS officials and representatives were often strained–both Chavez and Callahan were scolded and chastised by Representatives from both parties. Reps. Billy Long (R-MO), Meehan, Jackie Speier (D-CA), and Bennie Thompson (D-MS) all pointed out issues relating to what they variously saw as potential First Amendment violations, surveillance of citizens engaged in protected political speech, the fact that an outside contractor handles DHS’ social media monitoring, DHS’ seeming inability to separate news monitoring from disaster preparedness, and a massively unclear social media monitoring mandate on the DHS’ part.

Video footage of the hearing has already been made available on YouTube, and the written testimony of both DHS experts has been made publicly available. Privacy watchdog group EPIC also filed a formal disclosure to Congress on the results of a FOIA lawsuit. DHS appears to have also stonewalled EPIC regarding their social media monitoring project. The results are staggering.

According to testimony, the Homeland Security Department has outsourced their own social media monitoring program to an outside contractor, defense giant General Dynamics. General Dynamics was the sole party to the original DHS contract, which was not offered to any outside parties–and Chavez was caught misleading the Committee about General Dyamics’ sole status.
