An official body — created by an act of law as the 9/11 Commission was — can shine a light on such possible scandals as:

— Why did Trump fire Defense Secretary Mark Esper on Nov. 9, and was this preceded by pressure from Trump or his designees to elicit Esper’s support for military assistance in his bid to retain power?

— What deliberations regarding an effort to reverse the results of the election is former Attorney General William Barr aware of, and what would sworn testimony and texts and emails show about the circumstances of his late December departure? This departure followed public criticism by Trump of Barr, and numerous news reports said it also followed extensive negotiations between Barr and White House counsel Pat A. Cipollone.

— What interactions between Trump or his surrogates with the U.S. Attorney for the Northern District of Georgia, Byung J. “BJay” Pak, occurred before Pak’s forced resignation on Jan. 4?

— What will testimony, emails and texts show about the precise nature of any communication that may have taken place between Trump, White House aides, or outside advisers to Trump and people who participated in the Jan. 6 insurrection at the Capitol?
