“The only one that can overturn a presidents power is the congress according to the emergency powers act of 1974.”
And they’d have to garner 2/3 of both houses to overturn his veto.
Folks: it would take LESS votes to impeach and remove a POTUS than overturn his veto.
Trump is now, essentially, a war time president. And a war time president of the US is the most powerful man in the world. And the governors under similar statutes the most powerful person in their state.
And both can act unilaterally...sometimes outside judicial review.
And in all cases under judicial delay.
The governors are in the same situation Like Katrina hitting NO That’s not federal situation. The mayor and the governor had all the power they needed and they choked. But you have to have power at the local level for local situations.
