WASHINGTON — President Trump’s lawyers have for months quietly waged a campaign to keep the special counsel from trying to force him to answer questions in the investigation into whether he obstructed justice, asserting that he cannot be compelled to testify and arguing in a confidential letter that he could not possibly have committed obstruction because he has unfettered authority over all federal investigations.
In a brash assertion of presidential power, the 20-page letter — sent to the special counsel, Robert S. Mueller III, and obtained by The New York Times — contends that the president cannot illegally obstruct any aspect of the investigation into Russia’s election meddling because the Constitution empowers him to, “if he wished, terminate the inquiry, or even exercise his power to pardon.”
