German pointed out how Comey broke the cardinal rule by commenting on uncharged behavior of President Trump which undermined his presidency before he took office.
The FBI under Robert Mueller undermined public confidence in justice while James Comey nearly destroyed it completely, a new book claims.
He threw out the safeguards that were brought in by the Church Committee in 1975 and brought about a 'new era of abuse' against citizens.
Mueller's FBI has silenced whistle-blowers and created many 'victims of the FBI' says German, who became an adviser to the American Civil Liberties Union (ACLU) after retiring and has written papers attacking the bureau.
Comey went further and 'dispensed with the illusion the bureau was impartial and apolitical' when he made his public comments about the investigation into Hillary Clinton's emails in 2016.
