President Trump told reporters Thursday that he has the “absolute right” to declare a national emergency to secure funding for his border wall and will “definitely” use that option if he’s unable to reach a deal with Democrats.

“I have the absolute right to declare a national emergency,” he said. “I haven’t done it yet. I may do it. If this doesn’t work out, probably I will do it, I would almost say definitely. This is a national emergency.”

While Trump has left the option on the table for days, more conservative members of the media have voiced hesitation and outright opposition to the idea, over fear of the precedent it would set for other presidents.
