"Federal
officials have serious questions about the credibility of a key witness
in congressional investigations of Hillary Clinton’s role in the sale
of a uranium-mining company to Russian interests, two sources
knowledgeable about the case tell Yahoo News.
The
witness, a Florida businessman and former FBI informant named William
Douglas Campbell, was considered so unreliable that prosecutors dropped
him as a witness in an unrelated case involving Russian uranium sales,
according to the sources."
