You haven't made a point yet other than "at some point the president said something or other was unconstitutional and later on he did some other thing so that must be unconstitutional too."
He clearly said he did not have the power to do anything beyond what he had already done, didn't he?
I'm trying to figure out if reading comprehension is the problem here.
“My job in the executive branch is supposed to be to carry out the laws that are passed. Congress has said ‘here is the law’ when it comes to those who are undocumented, and they've allocated a whole bunch of money for enforcement. And, what I have been able to do is to make a legal argument that I think is absolutely right, which is that given the resources that we have, we can't do everything that Congress has asked us to do. What we can do is then carve out the DREAM Act folks, saying young people who have basically grown up here are Americans that we should welcome. …
But if we start broadening that, then essentially I would be ignoring the law in a way that I think would be very difficult to defend legally. So that's not an option. … What I've said is there is a there's a path to get this done, and that's through Congress.” (9/17/13)
“I am the Champion-in-Chief of comprehensive immigration reform. But what I’ve said in the past remains true, which is
until Congress passes a new law, then I am constrained in terms of what I am able to do. What I’ve done is to use my prosecutorial discretion, because you can’t enforce the laws across the board for 11 or 12 million people, there aren’t the resources there. What we’ve said is focus on folks who are engaged in criminal activity, focus on people who are engaged in gang activity. Do not focus on young people, who we’re calling DREAMers …. That already stretched my administrative capacity very far. But I was confident that that was the right thing to do. But at a certain point the reason that these deportations are taking place is, Congress said, ‘you have to enforce these laws.’ They fund the hiring of officials at the department that’s charged with enforcing. And
I cannot ignore those laws any more than I could ignore, you know, any of the other laws that are on the books. That’s why it’s so important for us to get comprehensive immigration reform done this year.” (3/6/14)
