15 legal experts weigh in: Could Trump pardon himself?

Mark Tushnet, law professor, Harvard University

The president’s constitutional power to pardon “offenses against the United States” is limited only by excluding “cases of Impeachment.” A self-pardon for ordinary criminal offenses does not fall within that exception, on my understanding.

A self-pardon might well be outrageously improper (unless there was the prospect of charges brought by a rogue prosecutor, whom, for some reason, the president could not control by firing him or her), but the response the Constitution creates for such misconduct is impeachment, a political rather than criminal remedy.
