The Trump-Russia dossier: What we know
An explosive but unsubstantiated political research dossier on Donald Trump's links to Russia alleges that his aides colluded with the Kremlin ahead of the US election, and that Russia has compromising information of a sexual nature about Trump. What is the Russia dossier? The 35 pages consist of memos compiled before and after the November 8 election by a former British spy, hired to produce opposition research on the Trump campaign, first by a Republican rival of Trump and then later by people tied to Hillary Clinton's Democratic campaign.
