President Joe Biden is slated to take broad executive action to end the crisis that has rocked the southern border since he took office in 2021, a move that goes against his recent claims that he may lack the authority act unilaterally.

The White House is expected to announce an executive order Tuesday that effectively shuts down the U.S.-Mexico border to illegal immigration. Under the Biden administration, nearly 10 million non-U.S. citizens have been encountered attempting to enter the United States.
