Actually, Folks have already answered that question. A group of four retired 4-star admirals and three retired 4-star generals wrote an op-ed saying Trump abdicated his sworn duty to preserve, protect, and defend the Constitution of the United States.
Personally, I don't believe Trump was really doing nothing during the critical hours of the insurrection. Let's turn to the official White House photographs. Oh, wait, the official White House photographer was told explicitly "no photos." Also, as we know, there were no calls or texts logged on any of Trump's official phones. And of course there are those mysteriously deleted secret service texts.
Why would Trump explicitly order "no photos"?? Probably because they would have shown him talking on burner phones, thus violating the Presidential Records Act while practicing sedition. Burner phones? Seriously?? Yeah, John Bolton, in sworn testimony, recalls Trump talking about burner phones on several occasions.
