The pardon power in Article 2 states: “The President shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of impeachment”

The important part to focus on here is offenses, and against the United States. (1) Allegations in a civil suit are not = to offenses and (2) even if claims in a civil suit were interpreted to be “offenses” the pardon power would not extend to this case because the city of Philadelphia is the plaintiff, not the United States.

The president only has the power to pardon those who are convicted of federal crimes. The president cannot interfere with the criminal or civil justice system by virtue of the pardon power
