Republicans are stepping up pressure on the Justice Department to appoint a special prosecutor in the Hillary Clinton email investigation as the administration signals its intention to fall in line behind the presumptive Democratic nominee. If there was ever a case for an independent counsel, this is it, Rep. Tim Huelskamp, R-Kan., told the Washington Examiner Monday. If they don't appoint an independent counsel, I think that's almost, in part, an admission of guilt, Huelskamp added. If they weren't afraid of that, they would appoint an independent counsel. GOP lawmakers and activists have pointed to President Obama's decision to endorse Clinton and campaign alongside her as evidence that the Justice Department's investigation is vulnerable to at least the perception of political bias. Barack Obama endorses Hillary Clinton, campaigns for Hillary Clinton, but he expects us to believe he'll be impartial in investigating Hillary Clinton? Rep. John Fleming, R-La., told the Examiner.
