President Donald Trump issued a message to the Central American migrant caravan encroaching on the southern border, while speaking at a rally for Sen. Cindy Hyde-Smith.

Trump was in Biloxi to stump for Hyde-Smith (R-Miss.), who faces former Clinton cabinet official Mike Espy (D-Miss.) in a Tuesday runoff election.

"I have a simple message to the lawless caravans: Turn back now, go back home, we will not let you in," Trump said.

He said Republicans are "committed to halting this incursion" and defending America's "sovereign borders."

Trump also called illegal immigration "deeply unfair to American workers."

He praised ICE agents for their bravery and effectiveness, claiming that about 235,000 "aliens with criminal records" were arrested by the agency in recent times.

Trump also mentioned the case of Luis Rodrigo Perez, an illegal immigrant who was released last year by officials in Middlesex County, N.J. -- which Trump described as a "sanctuary" municipality -- and was recently arrested in connection with an alleged triple homicide in Missouri.

"Tomorrow's election is about safety [and] prosperity," he said.
