Yes you are correct.
In the mean time we will be waiting for the SC to rule. Well in 2 years Trump has yet to even have a proper ruling from the SC on his ability to control the border.
While we wait to hear from the John (I like Obamacare) Robert court), millions will just walk right in with a kid in tow, and when they learn it is not their child, we will pay to bring the true parents up.
But he has gotten a proper ruling. Look up Trump vs Hawaii.
