The question with Trump is, CAN WE GIVE THAT MAN THE POWER TO DO THESE THINGS?
The question with Biden is, SINCE HE APPEARS INCAPABLE OF DOING THESE THINGS, WHO IS DOING THEM?
This is why you’re being downvoted so much. Both of these men have been president for four years. There isn’t any question of who would do what or who’s capable of what. You’ve obviously not been paying any attention for the last eight years.
It’s all documented. You can look all of it up on any number of websites both official and unofficial.
The summary of presidential powers is great. But you’re incredibly naive with everything else.
