Sessions, who received large donations from the super PAC backed by Lev Parnas and Igor Fruman, who are accused of conspiring to “circumvent the federal laws against foreign interference by engaging in a scheme to funnel foreign money to candidates for federal and State office,” said in a statement Thursday he had no knowledge of the scheme described in the indictment against the two.
