This will accomplish nothing. Liberals on the 9th Circuit would immediately stay the ruling and it will be tied up for 1 to 2 years before the Supreme Court rules. Then of course it takes time to start construction assuming the Supremes rule in Trump’s favor which is no certainty at all considering Roberts has been swinging left.
This is a face saving way to show the base he did everything he could but in actuality it does nothing and admits defeat.
The Supreme Court can take the appeal from Trump Admin...immediately, as it is a national security issue.
Simple solution: start building in the 5th and 10th districts.
