George Carlin had a must see routine based on this. 225 members of Reagan admin forced to resign, indicted, etc.
Wikipedia has eight scandals listed with references. IranContra alone could fill a whole series of diaries. That doesn’t include the October surprise where Reagan supposedly prevented Carter from getting hostages released. A story about a secret meeting, from April 1991, sounds a lot like a tRump-Russia story. More about how George Will used a stolen Carter debate book to help Reagan is here.
Reagan was no puppet for Russia. And he told smoother lies than tRump. Usually. But his admin was extremely unethical, to say the least.
