Dump them all off on the WH lawn. “here joe, here are you new ‘peeps’. I take it will be feeding them and providing them with tents?”
As the Germans would say “verpiß dich joe”!
Better to dump them off in the National Mall, Washington, DC, and let Congress, White House, and USSC share the joy of housing, feeding, clothing, educating, and medicating the illegal aliens. When the Mall fills up, ship 'em to the nearby towns where the Deep State families live so they can share the joy as well.
