From the Document: "Recent media reports suggest that Special Counsel Robert S. Mueller III is close to concluding his investigation of Russian interference in the 2016 election. As discussed in this separate Sidebar, Department of Justice (DOJ) regulations require the Special Counsel to deliver a confidential report (Special Counsel report) to Attorney General William Barr at the conclusion of the investigation, and the Attorney General must then notify Congress with 'an explanation' for the investigation's termination. But there appears to be no requirement in statute or regulation obligating the Attorney General to share the full Special Counsel report with Congress, and Mr. Barr has indicated that legal considerations might require him to withhold some or all of it. In response, some Members of Congress have suggested that a subpoena may be issued to compel disclosure of the full report."
