The special counsel, Robert Mueller, is examining tweets from President Donald Trump about Attorney General Jeff Sessions and the former FBI director James Comey to see if they played a part in attempts to obstruct the Russia investigation, according to the New York Times on Thursday. The report, which cites three people briefed on the matter, said Mueller wants to question the president about the tweets. Privately, some of Trump's lawyers think Mueller will make a case for interference with the probe by tying together some of the president's actions and tweets, the report said.
