Fox & Friends co-host Brian Kilmeade on Thursday cautioned President Donald Trump against declaring a national emergency to build a wall along the U.S.-Mexico border, stating it would be a “disaster and set “a terrible precedent.”

A partial transcript is as follows:

STEVE DOOCY: White House officials confidentially are saying this [declaring a national emergency] is probably the option [President Trump] is going to take. We’ve been telling you that for a number of days. He knows that if he tries to declare a national emergency on the southern border — that’s why he’s going down today, that’s the case he’s been making since the Oval Office address a couple of nights ago. His intent is to reprogram Department of Defense money, five billion dollars. Apparently, they’ve already found it. But he also knows that the Democrats will immediately challenge him in court — just like the DACA deal. And so, he expects that, but then, he would be able to re-open the government and then tell his supporters, “look, I did everything I could. If you want a clear victory, elect more Republicans to the Congress.”

BRIAN KILMEADE: It would just be a disaster in the big picture and just show us being inept and unable to govern around the world. And, it would just set a terrible precedent. They will continue — as Erik Erikson brought up, he said: “look, the next president, if it is a liberal president, will say a state of emergency will be climate change. Look at what happened with [Hurricane] Sandy, look at what happened with the earthquake, look at what’s happening to the polar bears, who’ve no place to walk on ice.” This would be a bad sign that the courts are forced to do something that politicians can’t, and that is come up with solutions to problems.

AINSLEY EARHARDT: Well, authorities down in Mexico realize that it’s a problem there in their country. as well. You always talk about the southern border down there. There are 12 legal ports of entry, that Southern side of Mexico, whether there are borders with Guatemala and Belize, and authorities have identified 370 additional illegal ports of entry. It’s not just a problem in our country, [it’s a] problem down there.
