TRUTH:

Mary Lincoln was a drug addict. John Wilkes Booth was well known at the White House because he was her supplier. Mary shot her husband. The bullet went in his head on the side sitting next to her.

Mary was removed from the country immediately after the assassination. She was taken to Europe. It is said she was institutionalized in an asylum (one of those HOSPITALS again) to get her off of drugs.

Mary returned to America several years later. Everything else is a cover-up to protect the image of the Presidency and that of America. A drug dealer, John Wilkes Booth, was sacrificed along with some Southern sympathizers to provide a cover story. History is NOT what you have been taught.

You can look it up.
