The Governor of the Commonwealth of Kentucky is the head of the executive branch of Kentucky's state government, and serves as commander-in-chief of the state's military forces. The governor has a duty to enforce state laws; the power to either approve or veto bills passed by the Kentucky General Assembly; the power to convene the legislature; and the power to grant pardons, except in cases of treason and impeachment. He or she is also empowered to reorganize the state government or reduce it in size. Historically, the office has been regarded as one of the most powerful executive positions in the United States.
