evidence: Encounters on the southern border of those trying to enter the U.S. without authorization have gone up significantly under President Joe Biden. Government statistics show that in the initial processing of millions of encounters, 2.5 million people have been released into the U.S. and 2.8 million have been removed or expelled. [...] Republican presidential candidate Nikki Haley, the former U.S. ambassador to the United Nations, claimed last month that 8 million "have come in illegally" and "we have to send them back." Florida Gov. Ron DeSantis made the same claim in a GOP debate in January. [...] DHS has released several spreadsheets of data on illegal immigration at the southern border. All of the figures in this story come from that data from the Office of Homeland Security Statistics, unless otherwise noted.
