Roger Stone's Commutation of Sentence

Stones testimony was made "in a case of impeachment". The constitution bars the President from using his pardon powers in such cases. Please have the law applied, to Barr and Trump. Stone's conviction was for lying to Congress and Mueller. Those investigations could only lead to impeachment since DOJ asserts the President cannot be indicted while in office. Consequently, the "case" Stone lied in was a case "of impeachment". Additionally, this commutation is arbitrary and capricious. There is no rational reason Stone should be have his sentence commuted. The President does not have the power to act irrationally. The Supreme Court has found that twice regarding this President. Just another Constitutional violation by the President of the United States, blessed and welcomed by the whole Republican Party and the whole Justice Department.
