No I didn't forget Andrew Johnson... Congress attempted to impeach Johnson under the premise that he removed someone from office without proper authorization. He did not deliberately attempt deliberate malfeasance and obstruction of justice like Slick Willy.

To wit:

Subsequent events vindicated Johnson's position that he was entitled to fire Stanton without Congressional approval. First, the Tenure of Office Act was repealed by Congress in 1887. More importantly, in 1926 the United States Supreme Court in Myers v. United States affirmed the ability of the President to remove a Postmaster without Congressional approval; in so doing, it stated in its majority opinion "that the Tenure of Office Act of 1867...was invalid"

So who's the fool now? Remember, name-calling is strictly the province of those who have run out of anything intelligent to say...
