"I can understand why the Biden administration would not want the American people to know what's going on," the South Carolina Republican told Fox News's Sean Hannity Monday night. "We'll have half of Central America in the United States in a year if we don't change these policies."
Graham, along with a delegation of nearly 20 fellow Republican senators, traveled to border facilities late last week and told Hannity Monday that the conditions in which migrant children are being held are "terrible," and that he saw people who were going to be freed promptly into the United States.
"I saw 200-plus women and small children being processed in front of me," Graham announced. "They were going to be released into the United States within 8 hours."
He continued and said that he witnessed children with numbers on their wrists, which means they have family members in the United States who are transferring money to Central America that's used to hire smugglers to take those children north.
"They hire a human smuggler, a human trafficker to get them to the border," explained Graham. "Once we catch them, your tax dollars are used to reunite with family. This is not catch and release. This is catch and reunite. They call the family member, the number on the child's wrist, and the American taxpayer pays to reunite the family who is here illegally. It will send the wrong signal."
Graham explained that he was warning about the future migrant flood even throughout President Joe Biden's transition into office.
He said he was being told by Border Patrol officials that Biden would be breaking outgoing President Donald Trump's policies on unaccompanied minors, and finishing the "remain in Mexico" policy that needed incoming migrants to stay south of the border while their asylum cases were pending.
Meanwhile, Graham announced that he's never seen as many incentives for illegal immigration as there are under Biden.
"If you have a family member here illegally, we're going to pay to reunite the family illegally," said Graham. "If you're 16 and younger, we're going to make sure you never leave the country. If you have a family member here illegally, we're going to pay to reunite the family illegally. That incentivizes people. Within two weeks you're released into the United States without a court date."
This means by summer, "we'll have 150,000 (people) per month," said Graham. "If they don't change the policies, nothing will change. It's only going to get worse."
