evidence: There aren’t 20 million to 30 million immigrants in the U.S. illegally, as Sen. Marco Rubio claimed [...] 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.
