Biden start at the wall project because the funds had been appropriated by Trump and could not be reappropriated to something else. Building a wall does not stop illegal immigration finishing a wall might but it's still unrealistic to build a wall across the whole Southern borderBiden restarted building the wall after he realized the border became a disaster after he halted building it. Even though he said he wouldn't build even another mile of wall.
I guess that also makes him a xenophobe.
And a liar right?
Parallels indeed.
