Well over a year after the FBI began investigating "collusion" between the Trump campaign and Vladimir Putin, Special Counsel Robert Mueller has brought in his first major indictment.

Trump campaign manager Paul Manafort has been charged with a series of crimes dating back years, though none is tied directly to President Donald Trump or 2016.

With a leak to CNN that indictments were coming, Mueller's office stole the weekend headlines. This blanketed the explosive news on a separate front, as the dots began to be connected on a bipartisan plot to bring down Trump that began two years ago.

And like "Murder of the Orient Express," it seems almost everyone on the train had a hand in the plot.

The narrative begins in October 2015.

Then it was that the Washington Free Beacon, a neocon website, engaged a firm of researchers called Fusion GPS to do deep dirt-diving into Trump's personal and professional life – and take him out.

A spinoff of Bill Kristol's The Weekly Standard, the Beacon is run by his son-in-law. And its Daddy Warbucks is the GOP oligarch and hedge-fund billionaire Paul Singer.

From October 2015 to May 2016, Fusion GPS dug up dirt for the neocons and never-Trumpers. By May, however, Trump had routed all rivals and was the certain Republican nominee.

So the Beacon bailed, and Fusion GPS found two new cash cows to finance its dirt-diving – the DNC and the Clinton campaign.

To keep the sordid business at arm's length, both engaged the party's law firm of Perkins Coie. Paid $12.4 million by the DNC and Clinton campaign, Perkins used part of this cash hoard to pay Fusion GPS.

Here is where it begins to get interesting.
