This is the week we know, with increasing certainty, that we are entering the last phase of the Trump Presidency. This doesn’t feel like a prophecy; it feels like a simple statement of the apparent truth. I know dozens of reporters and other investigators who have studied Donald Trump and his business and political ties. Some have been skeptical of the idea that President Trump himself knowingly colluded with Russian officials. It seems not at all Trumpian to participate in a complex plan with a long-term, uncertain payoff. Collusion is an imprecise word, but it does seem close to certain that his son Donald, Jr., and several people who worked for him colluded with people close to the Kremlin; it is up to prosecutors and then the courts to figure out if this was illegal or merely deceitful. We may have a hard time finding out what President Trump himself knew and approved.

There is no longer one major investigation into Donald Trump, focussed solely on collusion with Russia. There are now at least two, including a thorough review of Cohen’s correspondence. The information in his office and hotel room will likely make clear precisely how much the Trump family knew. What we already know is disturbing, and it is hard to imagine that the information prosecutors will soon learn will do anything but worsen the picture.

Of course Trump is raging and furious and terrified. Prosecutors are now looking at his core. Cohen was the key intermediary between the Trump family and its partners around the world; he was chief consigliere and dealmaker throughout its period of expansion into global partnerships with sketchy oligarchs. He wasn’t a slick politico who showed up for a few months. He knows everything, he recorded much of it, and now prosecutors will know it, too. It seems inevitable that much will be made public. We don’t know when. We don’t know the precise path the next few months will take. There will be resistance and denial and counterattacks. But it seems likely that, when we look back on this week, we will see it as a turning point. We are now in the end stages of the Trump Presidency.
