Lawmakers press Homeland Security on Internet monitoring

Leaders of a congressional subcommittee are urging the Department of Homeland Security to extensively monitor social media sites like Twitter and Facebook to detect "current or emerging threats."

The top Republican and Democrat on a House counter-terrorism subcommittee last month sent a letter to Homeland Security's intelligence chief encouraging department analysts to pore over huge streams of social media traffic. Reps Patrick Meehan (R-PA) and Jackie Speier (D-CA) said in the letter to Caryn Wagner, undersecretary of homeland security for intelligence and analysis, that they "believe it would be advantageous for DHS and the broader Intelligence Community to carefully parse the massive streams of data from various social media outlets to identify current or emerging threats to our homeland security."
