JD Vance repeats inflated immigration figures rejected by experts

Republican vice presidential nominee JD Vance made a dubious immigration claim Thursday as he blamed Vice President Kamala Harris for failing to prevent more undocumented immigrants and asylum seekers from entering the United States.

Vance, the Ohio senator and running mate to former President Donald Trump, said on CNBC's "Squawk Box" that the Democratic presidential nominee "has flooded the country with 25 million illegal aliens."

But Vance's figure wildly inflates the facts, according to data from U.S. Customs and Border Protection and estimates from government agencies and other organizations that track border crossings and asylum claims.

Vance has spread the claim before. During an Aug. 28 speech in Wisconsin, Vance claimed Harris "let in 25 million illegal aliens." He specified in the same speech that those alleged 25 million people are currently "here in this country illegally."

The nonpartisan Migration Policy Institute arrived at a similar figure, saying in March that it "estimates there were about 11.2 million unauthorized immigrants in the United States in 2021, up from 11 million
