Border towns and cities have been begging Biden to see the crisis for himself and to do something about the overwhelm border towns and Border agents. Take El Paso for instance....Migrants have set up their own tent cities along the streets hampering the locals same as what is happening in other cities such as LosAngeles.
And now Biden will finally visit the Border today. Before hand though, the Biden brigade cleaned up the streets and chased who knows where the migrants away. Biden will not see the real picture of what is happening.

So sad, too bad for the American Citizens who live in the border towns and working ranches along the border.
