On Wednesday's broadcast of "NewsNation Now," John Sandweg, who served as acting ICE Director under President Obama, stated that the report that DHS identified more than 400 migrants who were brought to the United States by a human smuggling network affiliated with ISIS "highlights the vulnerabilities we're facing along our southern border," and said that "we need to tighten up things here, especially on the vetting on the front end, because almost all of these individuals were apprehended and ultimately released into the United States to await their immigration court hearings."
