After weeks of assailing reporters and critics in diligent defense of their boss, Mr. Trump’s team has been uncharacteristically muted this week when pressed about his explosive — and so far proof-free — Twitter posts on Saturday accusing President Barack Obama of tapping phones in Trump Tower during the 2016 campaign.
The accusation — and the F.B.I. director, James B. Comey, and the former national intelligence director, James R. Clapper Jr., emphatically deny that any such wiretap was requested or issued — constitutes one of the most consequential accusations made by one president against another in American history.
