Judge can. But I can't imagine what would make her allow the change.
Can Judge Berman be transferred to some other court by Barr, say Puerto Rico ?
No. Judges are appointed to a specific court.
It seems to me that all of Eeyore Muleface’s political prosecutions are fruit of the poisoned tree and every single one should be throw out because they are all predicated on the criminally fraudulent narrative of Russian collusion.
Julian Assange told Ellen Ratner he got the DNC emails from a Bernie Sandals supporting DNC insider, not the Russians (see her interview from Nov 2016). Seth Rich was a DNC insider and avid Bernie Sandals supporter.
Richard Grenell was just appointed acting director of national intelligence and may be able to see that Assange gets deposed (provide written testimony under oath about the source of the emails). The source likely was Seth Rich, but regardless, it most certainly was not the Russians, thus the entire Russia hoax was a feral government criminal fraud.
Stone and his team tried to pursue this in court, but political hack criminal judge Amy Berman didn’t allow it.
