FILE-- Attorney General William Barr testifies before a subcommittee of the House Appropriations Committee on Capitol Hill in Washington, April 9, 2019. After 23 months, 500 search warrants, 2,300 subpoenas and a string of indictments, the results of the investigation by the special counsel, Robert Mueller, will be public on April 17 in a nearly 400-page report. The treatise is likely to add significantly to our understanding of Russia’s 2016 election interference and President Donald Trump’s efforts to control federal inquiries into the matter. Barr has said four categories of information will be redacted from the special counsel’s report. (New York Times/The Minnesota Star Tribune)
