Who is Joseph Mifsud? A congressional source last week said, "I don't see any way the investigation can be aboveboard if Mifsud isn't a Russian agent."
Horowitz said all four of the FISA warrant applications for Carter Page relied upon a core probable-cause argument based on the idea that the FBI was conducting a legitimate investigation into Russian election interference.
Horowitz wrote that the "sole predication" for that investigation was a statement former Trump aide George Papadopoulos made to an Australian diplomat named Alexander Downer. Papadopoulos allegedly told Downer that a Maltese academic named Joseph Mifsud told him that Russians had "dirt" on Hillary Clinton.
Horowitz said that "if true," this first-hand account from a friendly foreign government was "sufficient to satisfy the low threshold" for opening an investigation. This was hardly the ringing endorsement of a "justified" probe many saw.
When Horowitz found no evidence that Mifsud "ever acted as an FBI [confidential human source]," pundits saw this as devastating to the Trumpian "conspiracy theory" that the FBI investigation was a setup.
Maybe, but the original conspiracy theory was that Mifsud was a Russian agent, and Horowitz, like Robert Mueller before him, found no evidence of this, either.GO READ THE WHOLE THING.
