This is how they are dealing with the crisis: they leak a story about how mad Biden is about it so he looks tough while they do nothing real.
You could walk into a room with twenty idea-people and put the task on the table, and there’s probably a hundred different variations of resolving this, but all would be drawing continual public attention and have a cost factor. Other than admitting in public you won’t allow any more migrants, and the work on the wall will continue....there’s no fix.
I would suggest this...if Biden-team can’t get a handle on this and it continues to escalate for all of 2021, and even going into the first half of 2022...the mid-term election is going to be about immigration and the failed Biden program. There’s probably forty House seats to flip because of this.
