What powers does the president have to excuse or forgive criminals?

The President of the United States has the constitutional power to grant pardons and reprieves for federal offenses, as outlined in Article II, Section 2 of the Constitution. This authority allows the president to excuse individuals from the legal consequences of their crimes, effectively forgiving them or reducing their sentences. However, this power does not extend to state crimes, which are under the jurisdiction of state governors or courts. The use of this power can be controversial and is often subject to public and political scrutiny.
