Answer:
The executive branch
Explanation:
Article II, Section 2 of the Constitution of the United States says that the President has the power to grant reprieves and pardon for offenses against the US except in cases of impeachment.
Alexander Hamilton explained in the pamphlet Federalist n. 74 that the reason why the Founders included the pardon in the US Constitution was that there should be a system of pardon so in cases of mistakes or unfair sentences this could be used.
