Bobulinski went on national tv (and probably said the same to the FBI) claiming to have met with Joe, Hunter, and Jim at a hotel bar (behind a pillar) during some convention, as a precursor to a business deal with Hunter and Jim. Does your daddy tag along to your business meetings too?
Now that doesn't prove Joe took money, but it does indicate Joe wasn't telling the truth about having no knowledge of or involvement in Hunter's businesses.
There's somewhere in-between a media blackout and running a hit-piece. The above is certainly worthy of real journalism seeking a response from Joe on the allegations. Bobulisnki is infinitely more credible than Kavanaugh's accuser and that story got wall to wall coverage. So "cautious about spreading misinformation" rings a little hollow when looking at how this story is still being treated.
