In a rare public statement in May, Robert S. Mueller III, the special counsel, tried to lower expectations that he might give any explosive testimony about his findings during the Russia investigation. Instead, he referred the public to his 448-page report.

“The report is my testimony,” he said.

That apparently didn’t satisfy Democrats in Congress, who subpoenaed Mueller to testify before the House Judiciary and Intelligence Committees, a spectacle that will take place this week and is sure to be closely watched.

Anyone eagerly awaiting Mueller’s appearance on Wednesday can get a preview of his findings in his report, which became an unexpected best seller this spring after several publishers released it in print.
