Rep. Michael McCaul (R-TX) noted that the recent “uptick” in terrorist attacks are coming with little warning.

McCaul appeared on ABC News’s This Week Sunday immediately following Department of Homeland Security Secretary Alejandro Mayorkas, who responded to the two acts of terrorism from earlier in the week. While Mayorkas claimed that these attacks were “not an issue of the border,” McCaul suggested that more attacks could be on the horizon as eight ISIS individuals entered the U.S. via an illegal border crossing.
