Over months of discussions about whether documents were still missing, some officials also came to suspect Trump’s representatives were not truthful at times, according to people familiar with the matter who spoke on the condition of anonymity to discuss an ongoing investigation.

On Tuesday, a lawyer for Trump said the agents who brought the court-approved warrant to Mar-a-Lago a day earlier took about 12 more boxes after conducting their search.

People familiar with the investigation said that Justice Department and FBI officials traveled to Mar-a-Lago this spring, a meeting first reported by CNN. The officials spoke to Trump’s representatives, inspected the storage space where documents were held, and expressed concern that the former president or people close to him still had items that should be in government custody, these people said.
