According to the quote in this story.

From the story:

FBI special agent Kathleen Nicolls said Loomis admitted the NARAS statements were false during an interview on August 15, eleven days before federal agents searched his Roseville offices and Granite Bay home. Agents hauled away hundreds of boxes of documents and dozens of computers.

During the August 15 interview with the FBI, Loomis admitted knowing Warren engaged in fraud while he worked for Loomis Wealth Solutions. But Loomis told investigators he never reported the fraud because he believed they were isolated incidents.
