A congressional committee hearing is being held today on the Homeland Security Department’s (DHS) monitoring of social media. The meeting, being convened by the House Subcommittee of Counterterrorism and Intelligence, chaired by Rep. Patrick Meehan (R-PA), is being held as a result of documents on DHS monitoring that were exposed through a Freedom of Information Act request by the Electronic Privacy Information Center (EPIC), a public research center that focuses attention on emerging issues of privacy and other civil liberties issues.
