From breaking into computers to paying for a megaphone, Russian efforts to undermine the U.S. political system have been spelled out in detail by special counsel Robert Mueller, who has described an elaborate campaign of hacking and propaganda during the 2016 presidential race.
While Mueller has yet to submit to U.S. Attorney General William Barr a final report on his investigation into Russia's role in the election, the former FBI director already has provided a sweeping account in a pair of indictments that charged 25 Russian individuals and three Russian companies.
Key questions still to be answered are whether Mueller will conclude that Trump's campaign conspired with Moscow and whether Trump unlawfully sought to obstruct the probe. Trump has denied collusion and obstruction. Russia has denied election interference.
