No.
A bunch of dudes with 50k posts on an anonymous message board claimed it was debunked. A few of them have law degrees, one of them from Duke, so they are given instant credibility without actually providing any facts.
Another guy has a "friend" who supposedly is "connected" in DC. This guy is known for fabricating stories, not sure why anyone would believe him.
I posted several links in the Russia thread the other day laying out exactly what happened, what was questionable, what was done about it.
The usual suspects all refused to read and comment on the links. They just informed me that so and so said it wasn't true and I was a troll because I was bringing up a topic that did not fit their conspiracy.
The U1 story is just getting warmed up. People can claim it was debunked all they want, but that will not change the facts.
If you are genuinely interested in U1 (and not just trolling with your post) I would recommend reading these two articles. They provide a good start on the corruption surrounding U1.
