To be clear: There is zero public evidence that Trump's claims are anywhere close to the truth. What we know is that the FBI used a confidential human source to talk to several Trump campaign advisers, including Carter Page and George Papadopoulos, during the campaign. The bureau did so because it had concerns about conversations those two men had with Russians. The confidential source was deployed to suss out what the Russians had told Page and Papadopoulos so as to gain insight into Russian meddling efforts. The source was never "placed" or "embedded" in Trump's campaign. That's what we know, according to knowledgeable sources who have spoken *NM*
