That quote, though, is much older. It is from an IRS agent addressing officials of a conservative organization that was being audited during Bill Clinton's presidency. This illustrates that the use of federal agencies to punish presidents' enemies did not start with President Trump.

The administration of President Franklin Delano Roosevelt used tax investigations against political opponents. Targeted individuals included publishers of newspapers that were highly critical of Roosevelt's domestic and foreign policies.

President John F. Kennedy used the IRS and the Federal Communications Commission (FCC) to drive his conservative critics off the radio. President Lyndon Johnson also used the IRS and the FCC to silence conservative critics. One tool that was used to silence conservatives was to accuse broadcasters of violating the "fairness doctrine" by favoring conservative commentators.

President Richard Nixon used the IRS to target political enemies. The Nixon administration also threatened television and radio companies with revocation of their broadcast licenses unless they provided favorable coverage of the administration.

During the Clinton administration, the IRS not only targeted conservative and libertarian organizations it audited Paula Jones after she sued President Clinton for sexual harassment.

During the George W. Bush years, the IRS targeted organizations critical of the Iraq War. When Barack Obama assumed the presidency, the tax agency turned its attention back to conservative and libertarian groups, with a focus on organizations associated with the Tea Party. The Department of Homeland Security also issued a warning that those with pro-liberty bumper stickers — including supporting the Libertarian Party or my presidential campaign — might be violent extremists.
