“In short, unless there is a smoking gun against the president that is lurking unseen even in the private jousting between Trump’s team and Mueller, the special prosecutor should be wrapping up the obstruction aspect of his probe rather than extending it via a court fight over the president’s testimony.”
We learned more about the back-and-forth between President Trump’s legal team and Special Counsel Robert Mueller this past weekend. The New York Times published a long letter from Trump’s team to Mueller arguing that he should drop his request to interview the president.
The lengthy letter makes many factual and legal assertions, some of which are highly debatable. Yet, assuming that it accurately reflects the nature and scope of Mueller’s investigation, its two bottom-line claims have merit: The special counsel does not have a viable criminal case against the president, nor has he justified the extraordinary measure of seeking the president’s testimony.
The letter suggests that the special counsel’s inquiry into Trump’s conduct is focused on obstruction. Mueller was appointed on May 17, 2017, amid the uproar over two events: Trump’s May 9 firing of Comey, and Comey’s subsequent leak of a memo-to-self (published by the Times on May 16), which claimed that Trump had pressured him to drop any investigation of former national-security adviser Michael Flynn. The letter implies that these two events remain the gravamen of the special counsel’s obstruction probe. If that is so, there is no obstruction case.
Only illegal acts to influence an investigation can predicate a criminal charge of obstruction against a president. Investigation and prosecution are executive functions in our system. FBI investigations are conducted under the president’s power; unlike ordinary citizens, the chief executive has the authority to influence, impede, and even shut down investigations.
