When asked to define impeachable offenses, almost all of us would respond, “high crimes and misdemeanors.” I use the term “impeach” in what has become the common parlance, incorporating the two procedures of Congress that result in removal from office.
The full sentence in Article II section 4 of the the United States Constitution reads,
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.
“Bribery is defined by Black's Law Dictionary as the offering, giving, receiving, or soliciting of any item of value to influence the actions of an official or other person in charge of a public or legal duty” It was a conceptual dead end that Trump was challenged on the emolument clause of the constitution, which as this Washington Post article describes did not apply.
Unlike the emoluments proscription, the crime of Bribery is not based on accepting a gift or honor from a foreign country, rather it is the receipt of any item of value that influences the actions of one charged with a public duty — which for the office of President it is to advance the interests of the United States of America.
None of the occupants of this position have combined the duties of the Presidency with being the chief executive and principle owner of a global profit making enterprise, where performance of presidential duties can result in accrual of personal fortune.
The dereliction and abuses by this President before taking office are not a constitutional cause of action for impeachment, but the accrual of wealth of The Trump Organization at the least presents numerous conflicts of interest, that any single example being proven, is a specific stated Constitutional reason for his removal from office.
