"I want to do it faster. I could do the wall over a longer period of time. I didn’t need to do this, but I’d rather do it much faster…. I just want to get it done faster, that’s all."

That's something Trump said while explaining his need to use emergency powers, and as MSNBC's Steve Benen puts it, it's "probably the one thing Trump will regret saying."

It will be used as evidence that not only that it's not an emergency but that at the time of deciding to rely on the concept of emergency, he himself did not believe it's an emergency.

Of course, the lawsuits have already started.
