Good evidence and sources are utilized here. You could delve deeper into whether or not Donald Trump has "engaged in insurrection or rebellion" or has "given aid or comfort" to insurrectionists. I would suggest using the Constitution and its clauses—particularly those within the First Amendment—to determine if Trump is indeed considered an insurrectionist in the eyes of our Constitution and Bill of Rights, which serve as the primary sources for all things concerning the functioning of our nation's government.
There is no better way to fact-check a claim than to examine the primary source itself. There's no need to rely on CNN or the New York Times in this case; interpreting the Constitution and amendments can be done directly from the source
