Speaking of ChatGPT. I asked it if the "Can the President pardon someone that hasn't been charged with a crime?"
No, the president cannot pardon someone who hasn't been charged with a crime. The presidential pardon power, granted by the U.S. Constitution, specifically applies to individuals who have been convicted of federal crimes. It is meant to provide forgiveness for offenses already committed and does not extend to people who have not been formally charged or convicted.
That being said, the president can issue a pardon for someone who has been convicted but is seeking to avoid the penalties associated with their conviction, even if they haven't served time yet or are still in the legal process. But for someone with no charges or conviction, a pardon wouldn’t apply.
As I understand it, there is nothing in the Constitution that prohibits the President from issuing a preemptive pardon (although there should be). And Biden clearly gave preemptive pardons. This is why you should never rely on ChatGPT for anything factual.
