I agree. Some right wing journalist or somebody from True the Vote should investigate this further. Like I said, if they have the geolocation data for the phones, then it shouldn't be too hard to figure out where these people live and work and interview them. Then again now-a-days journalism is at best biased half-truths and usually little more than party propaganda and conspiracy theories. Why should we expect these folks who are supposedly so concerned about honest elections to finish the job? They've got enough for a conspiracy theory and that's good enough in today's media.
And in defense of D'Souza, why should he finish the job? It would be the morally correct thing to do, but Denish D'Souza has demonstrated "ethical flexibility" in the past; especially where elections are concerned. The people were going to believe still believe him regardless of how flimsy his story is. If it turns out he's wrong, he'd be hated by both the and the right, so his days doing political documentaries would be over. And if D'Souza did hunt down the mules and could prove there were ballot stuffing operations in key states, the vast majority of Dems/liberals would still reject it. Additionally, if D'Souza did find out that there was no ballot stuffing or perhaps some of these mules were stuffing the box for Trump, then he'd really be screwing the man who pardoned him for committing election fraud.
