Donald Trump’s campaign billed the event at a Michigan manufacturing plant as an address by the Republican presidential candidate on the local economy. Residents of the battleground state, aides noted in advance, were being hit hard by inflation.

But with rolls of insulated building materials as a backdrop and workers in the audience, Trump spent the first 25 minutes of the speech on Sept. 27 railing about border security and migrants streaming into the country. His words grew increasingly graphic as he did so.

Migrants who had come across the U.S. border were slaughtering people across the country, he falsely claimed.

“These are people at the highest level of killing that cut your throat and won’t even think about it the next morning,” Trump told the crowd. “They grab young girls and slice them up right in front of their parents.”

The Trump campaign did not respond to questions on what evidence Trump had to support those statements.
