Over the weekend, ABC News reported that the FBI and DHS are both taking domestic action in an effort to protect the homeland:
The Department of Homeland Security is increasing security measures at airports, train stations and other transportation hubs, and expanding scrutiny of visitors coming into the United States, two officials told ABC News.
The FBI, meanwhile, is “working sources” and taking other “logical steps” to monitor any potential threat, an FBI official said.
The embassies were closed. High alert worldwide because of "chatter". Why? So DHS and the FBI can add "logical steps" in the US?
