The two have faced scrutiny since last year, when the Federal Bureau of Investigation found a cache of classified documents at Mr. Trump's Mar-a-Lago estate during a court-authorized search. In a court filing after that search, the Justice Department said the discovery of documents during the Aug. 8 search "cast serious doubt" on a sworn statement Ms. Bobb had signed in June attesting that all materials requested by a subpoena to Mr. Trump had been turned over to the Justice Department. In fact, more records were later retrieved from the property.
