Trump hammers on ‘migrant crime.’ The reality: It’s not rampant, but a real concern.

In the closing stretch of the election, former President Donald Trump continues to emphasize claims of “migrant crime.” On Friday, he spoke in Aurora, Colorado, a city he charges is overrun by a Venezuelan gang. The Republican mayor has said such concerns have been “grossly exaggerated.”

Immigration is a top voter concern, polls show, and Mr. Trump has doubled down on assertions that unauthorized-migrant criminals are endangering U.S. citizens. He’s also raised the profile of murder cases, such as that of Laken Riley, in which the suspects are immigrants who authorities say entered the country illegally.
