If there were a hall of fame of legal self-owns, there would be a spot of honor for a line Friday from President Donald Trump as he announced that he would declare a national emergency to fund a wall on the U.S.-Mexico border.

To do so, Trump plans in part to use the National Emergency Act of 1976, but he undercut his argument that it was an emergency at all.

“I didn’t need to do this,” Trump said from the Rose Garden, “but I’d rather do it much faster.”

The next sound was lawyers across the country frantically adding Trump’s words to lawsuits to stop the president’s action. “Whatever a national emergency may be, that’s not it,” Supreme Court litigator Neal Katyal said. “That quote is going right in the lawsuit.”

And there was little doubt about how prominent it should be. “That’s plaintiffs’ Exhibit A,” said Elizabeth Goitein, a national security expert at the Brennan Center. “Consider putting this on page 1,” Supreme Court litigator Deepak Gupta tweeted to any lawyers crafting petitions.
