Mayorkas on Possible ISIS-Tied Migrants Crossing: That Happens 'Every Year,' We're Doing Stronger Vetting 'Than Ever'

On Wednesday's broadcast of "CNN This Morning," DHS Secretary Alejandro Mayorkas commented on the arrest of eight Tajik nationals with alleged ISIS ties who crossed over the border by saying that "every year, every single year, we encounter individuals that do, indeed, pose a threat to our public safety. That is not something unique to this administration." And "In fact, in this administration, the different agencies and departments across the federal enterprise are working more cooperatively and more effectively and doing more robust screening and vetting than ever before."
