President Trump said Saturday that Democrats want more caravans like the one making its way from Honduras to the U.S.-Mexican border.

“The Democrats want caravans, they like the caravans,” Trump told a crowd at a daytime rally in Nevada Saturday. “A lot of people say, ‘I wonder who started that caravan.’”

Trump thanked Mexico for coming to an agreement where they would help stop the caravan of approximately 4,000 migrants from easily making its way to the southern border of the U.S, and said he believes the whole situation is sad.

“Did anybody see that bridge over the weekend?” Trump queried the crowd, referring to when migrants that reached the Mexican-Guatemalan border rushed over a bridge and tore down a border fence. “I mean is that an incredible situation? It’s sad — and honestly, it’s sad on both sides. We’re going to figure it out.”

Mexico requested aid from the United Nations High Commissioner for Refugees to establish shelters along its border with Guatemala where the U.N. could vet those claiming refugee status.

Those deemed to have legitimate claims to asylum would be transported to a host country that has an agreement with the U.N. refugee agency, which includes the U.S. The deal with Mexico also says the U.S. can send back to Mexico those who illegally cross the U.S.-Mexican border.
