Joe Biden has promised that if he’s elected president, he will set in motion on Day One the largest dismantling of U.S. immigration law enforcement in the history of the republic.

On the very day he’s sworn in as president, the oath for which includes a constitutional obligation to “take care that the Laws be faithfully executed,” Biden has pledged to begin a 100-day moratorium on deportations of violators of U.S. immigration law. When deportations resume on Day 101 of his administration, Biden has further promised that “from that point on, the only deportations that will take place are [for the] commissions of felonies in the United States.”
