A day after U.S. Customs and Border Protection officers closed the U.S.-Mexico border for more than five hours and fired tear gas at migrants, President Donald Trump touted the “nasty looking wires” installed on the border.

“Are we doing OK on the border, folks?” Trump asked a crowd gathered at the Tupelo Regional Airport Monday. “Not gonna have it. … We’re not letting people come into our country unless they’re coming in legally.”

Trump was in Tupelo to stump for U.S. Sen. Cindy Hyde-Smith a day before she faces Democrat Mike Espy in a runoff for the final two years of a six-year U.S. Senate term.

The crowd burst into chants of “build the wall” when Trump touched on immigration.

Other countries aren’t sending their best people, Trump said, “they’re not putting Elvis in there.”

“Democrats have become the party of caravans and crime,” Trump said. “True. When you have open borders, you have crime. When you have sanctuary cities, you have crime.”

Multiple studies have shown that immigrants are less likely to commit crimes than native-born citizens. Nationally, about 5.6 percent of inmates in federal, state and local prisons are foreign born. Immigrants make up about 13 percent of the country’s population.

Thousands of migrants are currently waiting in Tijuana for the chance to apply for asylum, but only about 100 applications can be processed each day, according to USA Today.

On Sunday, a small group tried to rush a border fence, with the scene turning chaotic as border officers fired tear gas into Mexico and some migrants threw rocks.

The mayor of Tijuana has declared a humanitarian crisis over the arrival of more than 5,000 migrants traveling in a caravan, according to the Arizona Republic.

“I don’t think we like open borders,” Trump said. “They’re not coming through anymore unless they come through legally. If you want more jobs and less crime, then you have to vote Republican.”
