On Tuesday, CNN reported that President Obama and President-elect Donald Trump were given a two-page dossier detailing findings that Russia has "compromising personal and financial information" about Trump. Meaning, they have shit on him they could, conceivably, threaten to use against him.
Buzzfeed went ahead and posted the entire document online and it's definitely questionable—it's unverified (lol, good luck verifying this stuff), highly salacious, and even contains spelling errors (which, presumably, official government documents should not contain). Supposedly, the report was prepared for Trump opponents by a former British intelligence agent.
