“This is a masterful stroke by Texas,” said Josh Blackman, an associate professor at South Texas College of Law. He said Mr. Trump has been trying “to have it both ways” but will now have to choose.

“If Texas decides to litigate this, you’ll now have the Trump administration defending in court an illegal program that they said is illegal,” he said.
If Trump does decide to fight the 10-state coalition on this, it will really put Attorney General Jeff Sessions in a tough spot. Sessions doesn't support DACA and never has. He has always been one of the programs most adamant opponents.

President Trump put himself in this huge pickle barrel, now it'll be interesting to see how, or even if, he'll climb out. Either way, he still broke his promise to those of us that voted for him.
