Subject: Re: Biden/s Sttatement on the Pardon
I noticed that the specific power granted to the President by Article II, Section 2 of the U.S. Constitution is:

"[The President] shall have Power to Grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment."

What's the definition of an "offense against the United States"? Is it just the breaking of a Federal law? What if someone is in jail for a state crime and not a federal crime? Can the President pardon them?
