PapaD was honey-trapped by Mifsud.
No surprise, but this operation started in early March.
My sense is that it was a CIA financed operation, with the goal of Halper then innocently 'informing' the FBI.
Information laundering.
Some in the FBI, like Bill Preistap, might not have been aware of the CIA/DoD payments and legitimately thought this was a lead.
Did they also not do their homework on Mifsud?
