Former president Donald Trump on Sunday accused undocumented immigrants of waging an “invasion” of the United States, in a speech that highlighted his frequent use of dehumanizing language and exaggerated terms to describe many foreigners seeking to enter the country.

During a campaign event in Reno, Nev., the clear polling leader in the Republican race blamed President Biden for what he portrayed as a dangerous incursion on the homeland — although many migrants detained at the southern border are parents and children seeking protection, and studies show that undocumented immigrants are less likely than U.S. citizens to commit crimes.

“This is an invasion. This is like a military invasion,” Trump said. “Drugs, criminals, gang members and terrorists are pouring into our country at record levels. We’ve never seen anything like it. They’re taking over our cities.”
