Congress approved five bills providing funding for defense, energy and water, labor, Health and Human Services, the legislative branch and Veterans Affairs. Trump signed those into law.
The bills that need approval would fund the Departments of Agriculture, Commerce, Justice, Homeland Security, Interior, State, Transportation and Housing and Urban Development, as well as several smaller agencies. These are the shutdown targets.
DHS is not funded...Border Control\ICE comes under their umbrella.
If there is a shutdown, can’t have a totally open border.
Does the military replace border patrol ?
They might have to work for delayed pay. Bureau of Prisons do.
Then President Trump should have vetoed every one of those funding bills unless they contained a portion of his 5 billin minimum he wants for the wall. He also missed a big opportunity to get two weeks worth of his 5 billion in the continuing resolution. That would be over 192 million
