He not only has authority, he has the duty !
And the courts have nothing to do with this.
Sadly, he is probably the only American president ion recent times to understand and be willing ti enforce our borders.
“he has the duty !”
Precisely. As Commander in Chief, his primary duty is protection of our borders from any and all invaders, intruders, insurgents, trespassers.
He also has the authority to build a wall without the approval of the Rat/RINO treason party.
Your point is enormously important. By following many of the injunctions issued by these District Judges the President risks dereliction of duty via compliance. It would be no excuse to say a District Judge issued a worldwide injunction that prevented me as Commander in Chief from carrying out my duties. Instead the rightful answer in such a case. would be impeachment.
