Sen. Lindsey Graham recently went down to the U.S.-Mexico border, and what he saw alarmed him.

The South Carolina Republican didn’t moan about conditions or drinking fountains. Instead, Graham declared the current U.S. policies are making America vulnerable.

“This is a sick system, it’s rotten to its core,” Graham told host Maria Bartiromo on “Sunday Morning Futures.”

Graham said that some 30% of foreigners who illegally cross the U.S. with children are “fake families,” and that “children are being exploited.” He said some of the children are used over and over again to get adults into the U.S. “The word is out in Central America,” he said.

“Our laws are set up such so that if you can bring a small child to America coming from Central America, we can only hold the child for 20 days, then we let the entire family go because we don’t want to separate families,” Graham said.

He said 52,000 people have been released into the U.S. at the center he visited on the border.

On his visit, he said he also heard that at least 60 children who were released later came back with different “parents.”

“They pick the child up in Central America, they bring them to the United States, everybody’s released, and the child goes back to Central America to do it again,” he said. “They’re taking this journey, God knows what happens to them along the way.”

But wait, it gets worse.

Graham, who is chairman of the Senate Judiciary Committee, also said fraud at the border is so bad that “a terrorist could easily get in this group.”

“This will never stop until we change our laws,” he said, adding that a bill he will soon propose “will put the smugglers out of business.”
