President Donald Trump embarked on an odd tangent while describing the security measures being implemented at the U.S. border in anticipation of the caravan of Central American migrants.

Trump, at a rally in Montana on Saturday, said the caravan contained “criminals” who “threw stones at the police’s face” when they crossed the border from Guatemala into Mexico.

“We have our military now on the border,” Trump said, as the rally crowd cheered. “And I noticed all that beautiful barbed wire going up yesterday. Barbed wire, used properly, can be a beautiful sight.”

Trump was referring to the temporary barriers being set up by the military he dispatched to the border. The caravan, which counts around 4,000 now according to reports, remains hundreds of miles from the U.S. border. Nonetheless, Trump has promised to make the caravan a top campaign issue going into the midterm elections next week, even calling for 10,000 to 15,000 troops to be sent to the border.

On Thursday, he said that troops should treat rocks thrown by migrants as shooting.

“Consider it a rifle,” he said. “When they throw rocks like they did at the Mexico military police, consider it a rifle.”

Trump walked back those comments on Friday, claiming he did not mean to suggest the military shoot migrants throwing rocks: “We’re going to arrest those people. That doesn’t mean shoot them.”
