Saw Martha MacCallum interview Rep. Eric Swalwell, another Collusion truther. He stated that most of the Steele dossier was verified. Martha was a bit dumbfounded. Couldn't believe what he said. Then, he hit her with "what hasn't been proven?" Proving a negative is, of course, impossible.
Remember the explosion of criticism and the lambasting of anyone and everyone that had said the least thing regarding Obama's birthplace even though Obama in one of his writings said he was born in Kenya and his brother produced a Kenyan Birth Certificate. Anyone questioning the legitimacy of the Birth Certificate from Hawaii or requesting an investigation into the Kenyan certificate or why Obama's statement in his writings, was summarily drummed out or cast out into oblivion and condemned to the nth degree.
Guess our truthers and conspiracies are quite selective.
