Whoever, owing allegiance to the United States, levies war against them or adheres to their enemies, giving them aid and comfort within the United States or elsewhere, is guilty of treason and shall suffer death, or shall be imprisoned not less than five years and fined under this title but not less than $10,000; and shall be incapable of holding any office under the United States.
So, there it is, the only crime that is laid out in the United States Constitution. Can Donald J. Trump be charged with Treason Against The United States? Of course, I am talking about this in reference to his decisions with the U.S. Congress' approved aid to Ukraine.
The part that stands out to me is 'adheres to their enemies, giving them aid'. The U.S Congress approved aid was held up for 3/4 of a year by President Trump. The reason given by the WH has been concern for corruption in Ukraine. This is not the what the facts are beginning to show, with testimony from 2 firsthand witnesses, with corroboration from others under oath. The 2 firsthand witnesses' testimonies show that Trump was withholding the aid for an agreement from Ukraine to publicly declare they were investigating Joe and Hunter Biden (Joe Biden was Trump's top rival for the U.S. Presidency at the time) for corruption, once again only at Trumps request.
If indeed it could be proven at trial in the Senate that Trump withheld the aid for reasons of extorting the Ukraine government to fabricate a corruption investigation involving Joe Biden, thereby damaging Biden, his chief rival for the Presidency of the United States, how could Trump be guilty of Treason Against the United States?
'adheres to their enemies, giving them aid'
By withholding the aid for Ukraine for 3/4 of a year in its war with Russia, this would have certainly, at least, be 'giving them aid', with "them" being Russia. With all the other Trump connections, and inexplicable siding with Russia, even against his own government Intelligence, and other U.S. agencies, this seems to be worth pursuing. As I said, under those circumstances laid out above, Russia, an enemy of the United States, was aided by the President of the United States, by withholding aid to Ukraine in a time of war with Russia. You may say 'but the U.S. was not at war with Russia', but congress approved aid for Ukraine in its war with Russia thereby solidifying its interests. Aiding Ukraine in its war with Russia, an enemy of the United States, was in the interest of United States.
There may proof out there to also support 'adheres to their enemies' by pursuing Trump's myriad of connections and decisions involving Russia.
Have at it.
