The President of the United States is not free to choose which laws he will enforce and which laws to ignore. He is bound by the oath of office to protect and defend the Constitution and enforce the laws.
This move to sever immigration law enforcement agreements with AZ in conjunction with the hot line the DOJ just opened for people to report AZ law enforcement officers who do ask for papers is one of the most under-handed things I could imagine an administration doing after winning the case in the Supreme Court. This is not just spiking the ball, this is doing a prolonged end zone dance and then openly taunting the opposing team.
We are not being led, we are being dictated to. This Administration does not deserve a second term!
