"This is a humanitarian crisis, this is a public health crisis," Cruz said. "The illegal immigrants who are being released, they are testing positive for COVID-19 at a seven times higher rate than the American population, and it is a national security crisis."

When a reporter asked Biden if what's happening inside the facilities is acceptable to him, he said, "That's a serious question, right? That's why we're going to be moving 1,000 of those kids out quickly."
