President Joe Biden’s orders to stop busting most criminal illegal immigrants are likely to cut arrests in half, leaving many sex offenders, drug pushers, kidnappers, and even murderers on American streets, according to an internal analysis of his initiative.

New data obtained by Arizona Attorney General Mark Brnovich showed that Biden’s effort to pause arrests of illegal immigrants already inside the nation, many in U.S. jails, will result in a 50% decline in federal captures and likely deportations of them.
