Donald Trump succinctly laid out the problem, then he called out both Chuckie and Nan to do the right thing. Then he let everyone know who is causing the problem of illegals killing innocent Americans.
I do believe that this was his shot across the bow. They have been warned.
Now, if he feels a declaration of emergency is warranted and emergency funding is gathered, Chuck and Nan are just going to have to eat it.
The “real problem” is that 53 GOP Senators have not marched over to the White House and demanded Trump declare a national emergency and use the military to build the wall. THAT would give POTUS leverage with the Dems. Unfortunately, the GOP doesn’t want a wall either so we get more useless beltway theater that will end with another stinking pile of garbage bill from Congress and “The Wall” tied up in court.
