‘Discussed infiltrating Mexican border’

A counter-terror official says ISIS militants have discussed the possibility of entering the U.S. via the Mexican border over social media, but says the Department of Homeland Security believes the border currently remains safe. Francis Taylor, DHS undersecretary for intelligence and analysis:

There have been Twitter and social-media exchanges among ISIL adherents across the globe speaking about that as a possibility. [DHS is] satisfied that we have the intelligence and the capability at our border that would prevent that activity.
