This week, the Biden administration announced that it will waive a series of federal laws to expedite construction of new barriers along the southern border with Mexico and, separately, resume deportation flights to Venezuela. The actions represent a striking reversal for a president who stopped construction of the border wall on the first day of his administration, after promising on the campaign trail that there would “not be another foot” built on his watch.  Biden defended the decision by his administration to build additional barriers along the border with Mexico, doubling down on the idea that he had no choice but to allow construction after Congress appropriated the funds in 2019, when Trump was president.
