This sounds like one of those more smoke than fire kind of stories. No doubt that Papadopoulos was up to something, but I also think investigations like this attract their own sets of grifters and hangers-on, so it would be good to be pretty skeptical of this info until more detail emerges. It could be a red herring thrown to the now Democrat-led investigative team as well.
Willing to take a polygraph test? Oh I definitely trust you now…
