This is a very good account of the down and dirty of the Trump dossier, and there was a lot of down and a lot of dirty. From George Szamuely at ronpaulinstitute.org:
The Trump-Russia collusion story was a joint invention of the Obama administration and the Clinton campaign. It enabled the Obama administration to make use of the nation’s security and intelligence services to spy on Trump and his associates and to use whatever information they thereby gleaned to try to get Hillary into the White House. The failure of the scheme didn’t stop either Obama or the Clintons. Following the election debacle, an enraged Obama administration sought vengeance by disseminating the dossier as widely as possible with a view to undermining the incoming Trump administration and to ensuring that no rapprochement with Russia would be possible. In doing so, Obama and Clinton have thrown American politics into turmoil and have perhaps pushed the United States and Russia toward armed confrontation.
We have known the basic outlines of the Steele dossier story since January. The Steele dossier, we have been told, started off as a piece of opposition research prepared by Fusion GPS and financed by a Republican rival of Trump’s or perhaps a GOP NeverTrumper. Following Trump’s victory in the GOP primaries, the Democrats took over its funding. Fusion hired Christopher Steele, a former head of the Russia desk at MI6 who now ran his own corporate intelligence firm, Orbis Business Intelligence. Using the leads Steele had developed during his years at MI6, he reported back to his paymasters his shocking discovery: The Russians had been cultivating Trump for years in preparation for his run for the presidency. So shocked was Steele by this that he rushed to alert the FBI, MI6 and even select reporters.
Most of this story is pure fiction. Neither the GOP nor a primary rival of Trump’s had any involvement with the dossier. To be sure, in October 2015, the Washington Free Beacon, a neo-conservative Web site funded by hedge fund billionaire Paul Singer, did hire Fusion to undertake opposition research on Trump. However, money for this undertaking dried up by May 2016.
