evidence: READ MORE: Biden’s new executive order denies asylum claims to most migrants crossing the border unlawfully "Eleven million? That's an outdated — that was the number 10 years ago," Rubio said. "We’re talking upwards of 20, 25, maybe 30 million. There’s been almost 10 million people that have entered this country in the last three years." Is Rubio right that the population of people living in the U.S. illegally doubled and has reached 20 million to 30 million? [...] Immigration officials don’t let in everyone they encounter, agents have expelled migrants millions of times under Biden. And the number of people living illegally in the U.S. is not static; it fluctuates as people die, leave the U.S. or change their immigration status. Adding the number of border stops under Biden to the estimated number of people already here illegally won’t produce an accurate total.
