To the editor:

Trump, in his pardon of Arpaio, has abused his power to pardon.

He has acted in violation of his duties as president under Article 2, Section 3 of the Constitution, which requires that he “shall take care that the laws be faithfully executed.”

He has flouted the rule of law and has laid waste to the hard work of the Public Integrity Section of the Department of Justice, which prosecuted Arpaio.

The father of our Constitution and former President James Madison described impeachment as the proper response to a president’s abuse of the pardon power. It is time for our Congress to act to remove Trump from office.
