Sen. Rubio warns of new ISIS threat at the southern border

(NewsNation) —  A newer, stronger ISIS is once again a threat to U.S. security, and one lawmaker says that threat is arriving via the southern border.

Florida Republican Sen. Marco Rubio is among the lawmakers sounding the alarm to stay vigilant on a possible attack by a rebuilt ISIS in the United States.

“They would love to do what they did in Moscow here inside the United States, and it’s something we have to be very vigilant about,” he told ABC’s “This Week.”
