A federal judge imposed a gag order on Friday in the case of Republican political consultant Roger Stone.

Judge Amy Berman Jackson ordered that lawyers and others in the case must not talk about it publicly in ways that "pose a substantial likelihood of material prejudice" and specifically they must not use the area outside court in Washington, D.C., as a venue for those kinds of statements.

In declaring a national emergency Friday, President Trump tried to underscore the urgency of what he calls a national security crisis along the U.S. border with Mexico, while at the same time downplaying the gravity of his response.

In a desolate stretch of desert outside Yuma, Ariz., there's a spot where more than 350 migrants and children burrowed under the steel border fence a few weeks ago.

"This only goes down just about probably another foot, this steel," said Anthony Porvaznik, chief patrol agent for the Yuma sector of the Border Patrol. He says smugglers tried digging in more than a dozen different spots, looking for places where the ground was soft enough.

"This is very sandy," Porvaznik said. "It's like that all the way down, and so it was easy to dig."
