Michael Cohen’s admission today in federal court that he committed felonies at the direction of Donald Trump exposes the president to criminal prosecution in New York State, an angle the mainstream news organizations have all missed.
State prosecution is a critical concern because Trump has the constitutional authority to pardon Cohen, or commute his sentence, for federal crimes. Trump claims he can pardon himself and continue in office.
Trump has claimed the power to fire Robert Mueller, the special prosecutor, or hobble his inquiry, and authority to take over the investigation and even run it himself.
But Trump has no power to stop any state-level criminal investigation or pardon anyone convicted of state crimes.
Justice Department guidelines prohibit indicting a sitting president, though he could be prosecuted after leaving office. No such restriction applies to New York and other state prosecutors, however, who are limited only by their willingness to act in the public interest.
