We have been told Donald Trump’s tweets are official statements from the president. They could also be the building blocks of an obstruction of justice case. Trump’s twitter feed has caught the eye of Robert Mueller. The New York Times reports:

“The special counsel, Robert S. Mueller III, is scrutinizing tweets and negative statements from the president about Attorney General Jeff Sessions and the former F.B.I. director James B. Comey, according to three people briefed on the matter.

Several of the remarks came as Mr. Trump was also privately pressuring the men — both key witnesses in the inquiry — about the investigation, and Mr. Mueller is examining whether the actions add up to attempts to obstruct the investigation by both intimidating witnesses and pressuring senior law enforcement officials to tamp down the inquiry.”

Quartz has put together a list of tweets “that could be clues for Mueller.”

Today on MSNBC Former Watergate prosecutor Jill Wine-Banks said she has long thought Trump’s Twitter account has held a lot of clues:

“It establishes a pattern of behavior and it shows what his intent really is. So it will be very helpful to see that as part of the evidence against the president. I have been saying for more than a year that the case for obstruction is in plain sight and part of it is that he talks to the public and he talks through Twitter and that is the same as if he approached someone in private. He’s sending a message to all these people, do what I want you to do or else. He could say that in a one-on-one meeting or he could say it through his twitter account, both of which amount to obstruction of justice and the president should be held accountable.”
