it was specifically a dubious account of a laptop supposedly belonging to Hunter
That is a lot of words to say that it was Hunter's laptop... As far as I know, there has not been any denial that the laptop wasn't in fact Hunter's nor that the contents of said laptop are not authentic, but the FBI has the laptop as of a year ago so I am sure it will come out eventually.
Most importantly of all, none of this has anything to do with the investigation into Hunter's taxes.
Given that the full extent of the investigation is not yet known, it seems premature to make such a claim. If Crackhead Hunter was picking up bags of cash he wasn't paying taxes on, then it may easily all tie together. I am not sure how he had time to be making all this money though, between the crack smoking, fathering a random child, getting kicked out of the Navy for testing positive for cocaine a month after daddy got him an age exemption at 43, or banging his dead brother's widow. Busy guy, but I am sure it is totally on the up and up and that daddy had no idea whatsoever...
This recent news does not in any way vindicate Trump's clumsy attempts to smear Biden as corrupt because of his son, nor does it cast a negative light on recent efforts to push back against bullshit fake news stories meant to smear Trump's rivals.
Which story is fake news?
It's so clearly irrelevant that I'm not even sure what the point of bringing it up was.
Given your glaring bias, I can see why you think it is irrelevant. Maybe spend about 30 seconds giving the matter some critical thought on your own and try again.
