In a campaign speech on Saturday in Des Moines, Iowa, U.S. Republican presidential candidate Donald Trump stated that he would crack down on immigrants who overstay their visas.

Trump also cited the shooting death of a cousin of NBA star Dwyane Wade to attract further support by African-American, calling it an example of violence that has to be addressed.

Trump attempted to clarify his views on how to overhaul the U.S. immigration system after stating before that he was softening on his plan to deport all 11 million illegal immigrants.

In his speech, said he would seek to institute a tracking system to ensure illegal immigrants who overstay their visas are swiftly removed.

“If we don’t enforce visa expiration dates, then we have an open border – it’s as simple as that,” he said.

In outlining his views, Trump said addressing illegal immigration is important to helping Americans find jobs.

“Every time an African-American citizen, or any citizen, loses their job to an illegal immigrant, the rights of that American citizen have been violated,” he said. “Equal protection under the law must include the consistent application of our immigration laws.”

As in regard of the death in Chicago of Wade cousin Nykea Aldridge, 32, Trump raised it as an example of turmoil in U.S. inner cities; an incident that paves the way for the Republican nominee to appeal to African-American voters who traditionally vote Democratic and overwhelmingly support Democratic rival Hillary Clinton.

“It breaks all of our hearts to see it, it’s horrible,” Trump said. “And it’s only getting worse. This shouldn’t happen in our country. This shouldn’t happen in America. We send our thoughts and our prayers to the family, and we also promise to fight for a much, much better tomorrow.”
