+The Special Counsel investigation (2017–2019), also referred to as the Mueller probe, Mueller report, Mueller investigation and Russia investigation,[1][2] was a United States law enforcement and counterintelligence investigation of the Russian government's efforts to interfere in the 2016 presidential election. According to its authorizing document[3] which was signed by Deputy Attorney General Rod Rosenstein on May 17, 2017, the investigation's scope included allegations that there were links or coordination between Donald Trump's presidential campaign and the Russian government[4][5] as well as "any matters that arose or may arise directly from the investigation". The scope of the investigation also included potential obstruction of justice charge by Trump and others within the campaign and administration.[6] Conducted by the Department of Justice Special Counsel's Office headed by Robert Mueller, a Republican and former Director of the Federal Bureau of Investigation (FBI), the Special Counsel investigation began eight days after President Trump dismissed FBI director James Comey, who had been leading existing FBI investigations since July 2016 into links between Trump associates and Russian officials. Following Comey's firing, over 130 Democratic Party lawmakers in Congress called for the appointment of a special counsel, while the FBI began investigating Trump for obstruction of justice. The special counsel's office took over both these investigations from the FBI.[7][8]
+
+For the criminal charges brought in this investigation, as of the investigation's conclusion in March 2018, 34 individuals received indictments for federal crimes. Seven of these individuals have entered guilty pleas or been convicted.[9] In August 2018, former Trump campaign chairman Paul Manafort was found guilty on eight felony counts of financial crimes in the United States District Court for the Eastern District of Virginia[10] and a month later pleaded guilty to conspiracy to defraud the United States and obstruct justice in a plea bargain for his full cooperation with prosecutors.[11][12] The investigation also led to Trump's former National Security Advisor Michael Flynn pleading guilty to making false statements to the FBI about his discussions of sanctions with the Russian ambassador during the Trump campaign,[13] and was required to be a cooperating witness in the investigations.[14] Mueller further secured guilty pleas from Manafort's business partner Rick Gates, Dutch attorney Alex van der Zwaan,[15] former Trump campaign adviser George Papadopoulos, lobbyist W. Samuel Patten[16] and Richard Pinedo.[17] Except Van der Zwaan, all have become cooperating witnesses for investigators. In February 2018, Mueller indicted 13 Russian citizens and three Russian entities, most notably the Internet Research Agency[18] and in June 2018 added an indictment of Konstantin Kilimnik, Manafort's business partner,[19] to whom he had passed internal campaign polling data.[20] In July 2018, 12 members of the Russian GRU cyber espionage group known as Fancy Bear, responsible for the 2016 DNC email hacking, were indicted.[21] Investigations into Trump's personal lawyer Michael Cohen were referred to the Attorney's office of the Southern District of New York.[22] Longtime Trump advisor Roger Stone was indicted on seven charges in January 2019.[23]
+
+Initially receiving bipartisan support,[24][25] the Special Counsel investigation was later criticized by Trump and his supporters. Trump has criticized people or groups related to the investigation over 1,000 times.[26] On January 30, 2019, an FBI court filing revealed that someone located in Russia was also attempting to discredit the Special Counsel investigation through Twitter.[27][28] Russian people have also sent falsified documents to reporters.[29] Some allegations of investigators' misconduct have been raised and were almost immediately debunked.[30] Trump and his supporters criticized the cost of the investigation. By December 2018, the investigation had cost approximately $25 million while gaining approximately $48 million through asset forfeitures.[31][32] The Special Counsel's office concluded its investigation and submitted the final report to Attorney General William Barr on March 22, 2019.[33]

+To rising nationalist and separatist movements, a referendum was held in March 1991, boycotted by some republics, that resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation. Gorbachev's power was greatly diminished after Russian President Boris Yeltsin's high-profile role in facing down a coup d'état attempted by Communist Party hardliners. In late 1991, Gorbachev resigned and the Supreme Soviet of the Soviet Union met and formally dissolved the Soviet Union. The remaining 12 constituent republics emerged as independent post-Soviet states, with the Russian Federation—formerly the Russian SFSR—assuming the Soviet Union's rights and obligations and is recognized as the successor state.[13][14][15]

The country had the world's second largest economy and the largest standing military in the world.[16][17][18] The Soviet Union was recognized as one of the five nuclear weapons states and possessed the largest stockpile of weapons of mass destruction.[19] It was a founding permanent member of the United Nations Security Council as well as a member of the Organization for Security and Co-operation in Europe (OSCE), the World Federation of Trade Unions (WFTU) and the leading member of the Council for Nominally a union of multiple national Soviet republics,[e] its government and economy were highly centralized. The country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic (Russian SFSR).
