Dossier suggest that a Trump-Russia quid pro quo was at the heart of the GOP's dramatic shift on Ukraine

An explosive findings from the dossier by a former British spy suggest that President-elect Donald Trump "agreed to sideline" the issue of Russian intervention in exchange to feeding Wikilieaks with hacked emails from prominent Democrats.

The dossier was part of an opposition-research project conducted by a former British spy, Christopher Steele, at the behest of anti-Trump Republicans and, later, Democrats. Steele was the former head of the Russia desk in Moscow for Britain's Secret Intelligence Service, also known as MI6. The memos he wrote made their way to US intelligence officials sometime last year.
