DHS privacy review rubber stamps their social media monitoring program.

The Department of Homeland Security released a Privacy Compliance Review which found that the DHS social media monitoring program complied the DHS's own privacy requirements. Documents obtained by EPIC through a FOIA lawsuit revealed that DHS is monitoring social networks and media organizations for criticism of the agency. Congress held a Hearing earlier this year to determine why DHS is tracking political statements on Twitter and social networks.
