Who was the only Vice-President of the U.S to be charged with treason?

Who was the only Vice-President of the U.S to be charged with treason? Now the Left-wing hate America bunch would say it should Dick Cheney, indeed, the New York Times, that source of great nonsense, had editorial Cheney should be changed as war criminal and the U.N agrees. Of  course, Cheney's crime isn't being a traitor to U.S but loving the U.S
Some might say Spiro Agnew, yes it's true Agnew was force to resign as Vice-President facing  criminal charges for taking bribes but not treason.
No, you have to go back to just about the becoming of the Republic to our third Vice-President Aaron Burr. An interest man, but had the devil inside maybe because he was grandson Jonathan Edwards the hell fire Presbyterian Preacher.
Burr was a man of great ambition but little or no belief, he become the boss of New York politics, indeed, one could say he founded Tammany Hall. Well, in the election of 1800 then Vice-President Thomas Jefferson who was running for President knew New York was key to his victory,henceforth, he team up with Burr so he would carry New York, which he did, however, the problem was both got 74 electoral votes, before the Twelve Amendment candidates for President didn't run as team, who got most electoral votes got Presidency and second got the Vice-President office provided they got majority. When Jefferson and Burr were the top vote getting but tie, the election went to House of Rep. where it remain deadlock until Alexander Hamilton back his arch-enemy Jefferson.
Of course, a few years later Burr had duel with Hamilton kill him and just about Burr's political career was over. Burr was man of great ambition he could no longer rule the United States, so why spilt the Western U.S off created a new country He got Great Briton to go alone until the English got government as Fox as foreign minster who recalled Anthony Merry as the U.K's representative to the U.S. Then a high U.S general Jams Wilkinson, who was in on the attempt to create a new nation, panic and told Jefferson of the attempt. The conspires base was in Ohio, an island own by Harman Blennerhassett, they were arrested, however, Burr was there, most likely  save him from a conviction, although he was arrested for treason , but government couldn't prove he acted overly, indeed, the verdict, so left handed, stating the government didn't prove it's case. But most people (and believe rightly so although the verdict was correct according to the law and Chief Justice Marshall rule correctly according to the law) thought Burr a traitor.
After the trial Burr left country, looking to enrich himself and flee credits,. Came back to U.S and late in life marry a rich woman( Jumel), but she saw though Burr and divorce him. Burr died a year in 1836, poor and disgraced.
