This is the most idiotic thing he's done yet. National "emergency"? Really ! If so, why did he:
1.) Spend billions of our tax dollars on a tax break for the wealthy instead of the wall (ie eliminating the estate tax)
2.) wait two years, when he had control of the house and the senate. (after all it was an "emergency" right ?)
3.) send home the coast guard and people who check criminal backgrounds, while not paying the TSA folks tying to prevent another 9/11
Answer:
This is being done because the wall was the first of many many lies to the American people and Trump's support is dwindling, as the wheels of justice are getting very, very, very close to the oval office. Once the government reopens, we will all know a lot more about his REAL motives, and I am betting they aren't American values.
