Duke Cunningham is a Military hero who helped create the "Top Gun" school. When he got in trouble for accepting gifts from lobbyists the vindictive anti-Military democrat party wouldn't just let him resign in disgrace, they wanted him in prison and they got their wish. It's ironic that John McCain was in the same kind of trouble during the Keating scandal but since the other four members of congress were democrats they let him go.
No, he took bribes, not gifts from lobbyists.
2.5 million in cash.
Some gift.
The Federal prosecutors that sent him to prison were Republican appointees.
Just because you are in the military does not make you immune from THE LAW.
