When will Biden or Harris go to the border and see the chaos they created?

I almost fell out of my chair when the Biden administration blamed Trump's immigration policies for the border situation, saying he "gutted" the regulations, which is ridiculous. All they had to do was continue his policies and this would not be taking place now. It's Biden's immigration policy and his invitation (since retracted) that caused the crisis. If they can't take full responsibility for the results of their actions, my level of respect for them (which is already low), will drop further.

whenever they want to

I would guess when they “create” chaos.
