 as Republicans re-upped claims that the southern U.S. border is too porous. But as NPR's Sergio Martinez-Baltran says, that's not true. It is true that under President Biden, the southern border saw a record high in terms of people crossing into the U.S. without authorization. But that number has really gone down since January. In June, there was a 24% decrease in arrests at the border in comparison to May. So, no, there has not been a quote-unquote open border or invasion at the southern border.
