The former congresswoman and National Guard soldier said Biden must return the border policy of former President Donald Trump.
"The Biden/Harris open-door policy has been a disaster. It needs to end now," she said. "The main beneficiaries of open borders are the gangs, cartels, and human traffickers."
"The Trump policy of having people wait on the other side of the border worked and needs to be reinstated," she said.
Gabbard's comments came in the wake of a surge of thousands of illegal Haitian migrants in Del Rio, Texas, and comprehensive reports of the Biden administration delivering unvaccinated and untested migrants throughout the country.

Refugees who make it across the river walk a short while to pass underneath the Acuña - Del Rio International Bridge, where overhead vehicles and pedestrians must pass through CBP inspection before being entered into the country.
At the start of this week, thousands of migrants began crossing and counting each day under the bridge, where they would wait to give in to Border Patrol and be taken to a federal holding station for processing and likely delivered into the U.S.
As for now, the amount of people crossing and making it to the bridge, which is on city land, is immense.
