The top two members of a House subcommittee want the Department of Homeland Security’s intelligence chief to keep a closer watch on social media traffic, says Reuters. Rep. Patrick Meehan (R-PA) and Rep. Jackie Speier (D-CA) pressed DHS Intelligence Chief Caryn Wagner to more carefully monitor users’ posts on sites such as Facebook and Twitter. Meehan is the chairman of the House Homeland Security Committee’s subcommittee for intelligence and counter-terrorism.
