The investigation of US citizen involvement in the Russian attack on our last election is just beginning. Whether Trump or any of his associates was involved remains to be seen. We know that Trump and several of his associates worked with and for Russians in high places in the Russian government - Rex Tillerson was presented a medal as a friend of the Russian state by Putin himself a few years back, when Tillerson was the CEO of Exxon Mobile.

This investigation isn't limited to proving or disproving collusion. Now it is just expanding into the legality of Trump's business activities and whether Trump is using his office to enrich himself in illegal ways. Two states have accused Trump of doing so, claiming harm to their states and their citizens. Robert Mueller is also looking into whether Trump obstructed justice by firing James Comey. Investigations of the Clintons lasted off-and-on for nearly thirty years, and came up empty-handed. These investigations may go on for years.
