Why did Biden finally decide to build more border wall?

President Joe Biden's decision to move forward with the construction of new border wall reflects a failure of his immigration policies amid widespread criticism ahead of next year's election.

The move, originally announced over the summer, first received widespread media coverage in October after Department of Homeland Security Secretary Alejandro Mayorkas waived more than 20 environmental laws, kick-starting the process despite the president's campaign promise not to continue the Trump administration's border policies.

Customs and Border Protection additionally outlined in August the dimensions and specifics for "up to 20 miles" of new border construction, which included "18-foot high, six-inch diameter bollards embedded into a movable, concrete, jersey barrier-style base system."
