Despite Weiss reiterating the same story to Garland in an attempt to mislead Congress, testimonies from several US officials suggest that the special counsel does not hold ultimate decision-making power. There have been too many complaints about the Justice Department's meddling in the investigation not to believe that there's a cover-up underway to protect the Biden family.
At first, Republicans demanded Trump-appointed Weiss to be named special counsel to independently investigate Hunter Biden as if this would finally make their conspiracy theories true. As that hasn't been the case, they are now pretending that there is something malicious going on to protect the Biden family instead of accepting that they have nothing against Joe Biden.
