Abuse of power or abuse of authority, in the form of "malfeasance in office" or "official abuse of power", is the commission of an unlawful act, done in an official capacity, which affects the performance of official duties. Malfeasance in office is often a just cause for removal of an elected official by statute or recall election. Officials who abuse their power are often corrupt. In the United States, abuse of power has been cited in the impeachment of at least five federal officials. Two of these (Judge George English and President Richard Nixon) resigned before their trial in the Senate could take place, and two others were acquitted by the Senate. The first impeachment trial of President Donald Trump concluded with the president being found not guilty on both articles of impeachment with one of them being the charge of abuse of power. At the state level, Governor Rod Blagojevich of Illinois was impeached and unanimously removed from office by the Illinois Senate in 2009 for offenses including abuse of power. Institutional abuse Institutional abuse is the maltreatment of someone (often children or older adults) by a system of power. This can range from acts similar to home-based child abuse, such as neglect, physical and sexual abuse, to the effects of assistance programs working below acceptable service standards, or relying on harsh or unfair ways to modify behavior. Impeachment of U.S. officials James Peck Federal Judge James H. Peck was impeached by the U.S. House of Representatives in 1830 on a charge of abuse of power. Peck had jailed a man for contempt of court after the man had publicly criticized him. The U.S. Senate acquitted him in 1831, with 21 voting guilty and 22 voting not guilty. Charles Swayne Federal Judge Charles Swayne was impeached by the U.S. House of Representatives in 1904. He was accused of filing false travel vouchers, improper use of private railroad cars, unlawfully imprisoning two attorneys for contempt, and living outside of his district. He was acquitted by the U.S. Senate in 1905. There was little doubt that Swayne was guilty of some of the offenses charged against him. Indeed, his counsel admitted as much, though calling the lapses "inadvertent." The Senate, however, refused to convict Swayne because its members did not believe his actions amounted to "high crimes and misdemeanors". George English Federal Judge George W. English was impeached by the U.S.
