Trump said he found the families taking pictures outside of his rally and asked them to come onstage and share their stories.
"He's going to do everything he says," Jamiel Shaw, whose son was shot and killed by an undocumented immigrant in 2008, said. "That's why everybody is so scared right now because they know change is coming. Change is coming."
Shaw has also appeared in a campaign ad for Trump, according to The Hill.
He also said Trump gave him hope from the moment he announced his run for President.
"We demand Americans first," Shaw said. "We don't care about illegal aliens. Americans first. First means first."
The other family members, part of the Remembrance Project, stood behind Trump and Shaw while they spoke, holding up posters with their family member's faces on them. Following Shaw's speech, Trump took the stage back to double down on his message about immigration.
"They all have a very similar story to tell, people that shouldn't have been here, people that should have never been allowed to come over the border and they come here like its nothing, they walk through it like its nothing," he said.
