Public office is a position of trust created by law to exercise portions of governmental authority for the benefit of the public. Key aspects of public office are that it is a public trust, not a property right or contract. The President, Vice President, and other high-level officials can be removed through impeachment for crimes like betrayal of public trust or corruption. The House of Representatives has the sole power to initiate impeachment cases and a vote of one-third is needed to bring the case before the Senate for trial.
