Did a federal judge sign the order?
Then it's a legal court order.
Congress writes immigration law not some Obama appointed judge. I would have ignored the order too. The sheriff is the law in any county, he alone can tell the feds to go F themselves if he wants. At least that was the intent when law enforcement rules were established.
Obama ignored all of that to try and pry open our borders, he should be indicted for what he did. I don't care if he was president or king of the world he was in the wrong. If Trump ever acted like the dictator Obama the left would go nuts and rightly so.
