At the heart of the issue is to disallow human traffickers a way into the US. We can not solve the world's problems but we can solve this one which adversely affects US citizens by allowing crime over our borders. My question is why were they not using DNA tests before?

TONY PERKINS: SESSIONS TALKING TO LAWMAKERS ABOUT USING DNA TESTS TO VERIFY PARENTS OF IMMIGRANT CHILDREN

“Sessions is talking to congressional members and is hoping for a legislative fix. The AG wants an immigration policy that is just, fair and enforceable. They talked about making sure that these really are the parents of these kids,” Perkins said.

He continued, “They are looking at how to use DNA tests in the field to verify they are parents and not traffickers. The reality is if American parents put their kids through what these immigrant parents have done to their kids — they would be charged with child abuse.”
