MARTHA MACCALLUM, "THE STORY" HOST: We have some breaking news for you tonight. Moments ago, Byron York reporting that we are now learning some more about who funded some of the early opposition research against Republicans and that was handled by Fusion GPS. Lawyers for the conservative publication The Washington Free Beacon informed the House Intelligence Committee, Friday, that some of that funding came from the Beacon. We're going to have more on that in just a moment. But let's go back now.

You remember, of course, that Fusion GPS took the fifth when they were questioned by Congress about their funding and their clients. We know that the latter the part of the research which resulted in the hiring of former MI-6 Operative Christopher Steele, and that subsequent dossier was paid for by the Clinton campaign with money that was filtered through a D.C. lawyer. The FBI has also been able to keep their connection to Fusion GPS concealed in the name of protecting the ongoing Mueller investigation.
