According to CNSNews:
Sen. Chuck Grassley, chairman of the Senate Judiciary Committee, is asking the Justice Department’s inspector general to examine whether “high-ranking” DOJ and FBI officials “compromised the public trust in the investigation into Hillary Clinton’s unauthorized use of a private email server as Secretary of State and potential mishandling of classified material.”
Several of those high-ranking officials had previous ties to the Clintons, he said.
Moreover:
Grassley named Attorney General Loretta Lynch, who met privately with former president Bill Clinton at a Phoenix airport in July, just days before the FBI announced it would not recommend the prosecution of Hillary Clinton. Grassley said Lynch’s meeting with Clinton “creates the appearance of a conflict,” given that she was appointed to the role of U.S. Attorney by then-President Bill Clinton and she was a partner at a law firm that represented both Bill and Hillary Clinton in their official government capacities.
