It's unclear on what grounds the president could sue over Mueller's findings, which were released by the Justice Department last April.

Trump, appearing to refer to the Stone case, tweeted it was conducted by "Mueller prosecutors," though only two of the four prosecutors on the case worked for the former special counsel. The president also inaccurately claimed that Mueller's investigation into Russian interference in the 2016 election was "illegally set up" based in part on a dossier of salacious allegations about him.

Trump also repeated his claim that Mueller came to the White House seeking the FBI director's job, a topic the former special counsel addressed in his 448-page report last year.

Former White House chief strategist Stephen Bannon told federal investigators that Mueller did not go to the White House seeking to become FBI director for a second time and was instead invited to offer “a perspective on the institution” to the president.

The president's tweets excoriating the Mueller investigation followed another set of tweets in which he singled out the judge overseeing Stone's trial.

Barr told ABC News last week that Trump never asked him to act in a criminal case, including Stone's, but that tweets about the Department of Justice and its employees “make it impossible to do my job and to assure the courts and the prosecutors in the department that we are doing our work with integrity.”
