That says removal, not indictment.YES YOU CAN INDICT A SITTING PRESIDENT!!! if the president is deemed an enemy of the united states and is proven to be a foreign agent OR deemed mentally or physically unfit....congress can do the 25th amendment to oust his ass and have the VP take over...
The Twenty-fifth Amendment (Amendment XXV) to the United States Constitution deals with issues related to presidential succession and disability. It clarifies that the Vice President becomes President (as opposed to Acting President) if the president dies, resigns, or is removed from office; and establishes procedures for filling a vacancy in the office of the vice president and for responding to presidential disabilities.[1] The Twenty-fifth Amendment was submitted to the states on July 6, 1965, by the 89th Congress and was adopted on February 10, 1967.[2]
