The Intercept reviewed a notice of the classified alert, which was sent out Friday afternoon by TSA’s Transportation Security Operations Center. A source, who reviewed the classified intelligence warning, described the threat as very general, with no specifics about location or type of attack — just the timing. The alert covers a 48-hour period that began late Friday afternoon.
The essence of the warning, according to a source, is that “ISIS plans an attack on U.S. soil.”
In response, the TSA deployed its Visible Intermodal Prevention and Response teams, or VIPR for short, to various locations. The VIPR teams have expanded in recent years, moving beyond airports to train stations and other busy transportation sites.
