Phone records belonging to FBI Director Kash Patel and White House chief of staff Susie Wiles were subpoenaed by the bureau back in 2022 and 2023 as part of a “massive targeting operation” undertaken by the Biden administration, The Post has learned.

The subpoenas were issued when both Patel and Wiles were private citizens, as special counsel Jack Smith probed President Trump’s handling of classified documents and his alleged efforts to interfere in the 2020 presidential election.

An FBI official told The Post that the information was contained in files found at the bureau’s headquarters in Washington, DC — similar to the “Arctic Frost” disclosures unearthed from apparent burn bags last year.

“It’s not just phone records and subpoenas — but a massive targeting operation,” the official noted, indicating the use of both technical tools and human intelligence. Several FBI employees were fired Wednesday related to the discovery.

The existence of the subpoenas was first reported by Reuters.

Patel and Wiles’ phone records were found in files labeled, “Prohibited,” according to the outlet.

“It is outrageous and deeply alarming that the previous FBI leadership secretly subpoenaed my own phone records — along with those of now White House chief of staff Susie Wiles — using flimsy pretexts and burying the entire process in prohibited case files designed to evade all oversight,” Patel said in a statement.
