Robert Mueller’s two-year, $25.2 million investigation was supposed to provide the definitive account of Donald Trump, Russia and the 2016 election. Yet even after he issued a 448-page report and testified for five hours before Congress, critical aspects remain unexplained, calling into question the basis for the probe and the decisions of those who conducted it.
