Years after the FBI closed several corruption probes into the Clinton Foundation, the IRS under President Donald Trump opened a criminal tax investigation into the foundation’s finances and its ties to other global charities. However, internal memos and emails obtained by Just the News reveal that the IRS abruptly cut off contact with key whistleblowers in spring 2019.

One memo noted that after weeks of communication, agents suddenly ended discussions with two whistleblowers, simply stating: “Can’t talk about the CF.” Among those sidelined was John Moynihan, a retired DEA financial crimes analyst, and Larry Doyle, a corporate tax compliance expert. Both had testified before Congress about potential misconduct involving the Clinton Foundation and shared evidence with the IRS.

Moynihan and Doyle are pursuing two whistleblower cases in U.S. Tax Court, one tentatively set for trial in December. Court filings reference IRS criminal investigation materials linked to their probe. IRS emails and notes show that from January to April 2019, whistleblowers met frequently with officials, who initially showed strong interest but later halted the investigation by July.

Internal documents reveal that a New Jersey IRS office considered formalizing Moynihan and Doyle as cooperating witnesses, with one investigator describing the foundation as “a fraud.” The documents indicate serious concerns within the IRS about the foundation’s activities.

Moynihan testified that the Clinton Foundation acted as an agent of foreign governments and should have registered under the Foreign Agents Registration Act (FARA). He argued the foundation was not entitled to its tax-exempt status, as it operated as a foreign agent throughout its existence.
