which branch of government has the power to pardon criminals
Pardon The pardon power of the President extends only to an offense recognizable under federal law.[29] However, the governors of most of the 50 states have the power to grant pardons or reprieves for offenses under state criminal law. In other states, that power is committed to an appointed agency or board, or to a board and the governor in some hybrid arrangement (in some states the agency is merged with that of the parole board, as in the Oklahoma Pardon and Parole Board).[30]
Federal Bureau of Prisons The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency. A subdivision of the U.S. Department of Justice, the BOP is responsible for the administration of the federal prison system. The system handles inmates who have violated, or are accused of violating, federal law. The BOP also holds inmates who have committed felonies in Washington, D.C.
