A delegation of Democratic lawmakers visited a U.S. Border Patrol station in New Mexico where an 8-year-old Guatemalan boy was held before he died last month. New York congressmember and new House Judiciary Committee Chair Jerrold Nadler blasted President Trump’s recent claims that immigration at the U.S.-Mexico border constituted a national emergency.

Rep. Jerrold Nadler: “The only emergency at the border is a humanitarian emergency caused by this war on children. The fact of the matter is that the number of apprehensions, the number of migrants crossing the border is way down over the last few years. There’s not an emergency of that nature.”

Meanwhile, Fox News host Chris Wallace challenged White House Press Secretary Sarah Huckabee Sanders Sunday on her claims that terrorists are entering the country via the southern border.

Press Secretary Sarah Huckabee Sanders: “We know that roughly nearly 4,000 known or suspected terrorists come into our country illegally. And we know that our most vulnerable point of entry”—

Chris Wallace: “Wait, wait, wait.”

Press Secretary Sarah Huckabee Sanders: —”is at our southern border, Chris.”

Chris Wallace: “Wait, wait, wait, because I know the statistic.”

Press Secretary Sarah Huckabee Sanders: “Yeah.”

Chris Wallace: “I didn’t know if you were going to use it, but I studied up on this. Do you know where those 4,000 people come—where they’re captured? Airports.”

Press Secretary Sarah Huckabee Sanders: “Not always, but certainly”—

Chris Wallace: “Airports.”

Press Secretary Sarah Huckabee Sanders: “Certainly a large number.”

Chris Wallace: “The State Department says there hasn’t been any terrorist that they found coming across the southern border from Mexico.”

Press Secretary Sarah Huckabee Sanders: “Certainly, it’s—it’s by air, it’s by land, and it’s by sea.”
