“...only to be impeached after lying about an affair...”
Revisionist history.
Clinton was impeached because he suborned perjury. He ordered other people to lie, under oath, while he skated. It is a criminal offense to induce someone to commit perjury.
Remember how he tried to explain what the word “is” is. Clinton should have been removed from office and imprisoned for raping Juanita Broaddrick.
Also because he committed perjury.
