[Logical me]

I wonder what would happen if Trump ignored the ruling.

Nothing. That insane judge has no army. Trump does.

"Waters of the U.S. Rule" is just that. It's a "rule" cooked up by the EPA and the Department of the Army.

It is NOT a law.

I'd imagine that it would be a pretty steep climb to force the President to do anything in this area.

In fact, if push comes to shove, Trump could really muck it all up and say that he's abolishing the EPA.

Might take their minds off the silly stuff for awhile.
