Special counsel Jack Smith's team has questioned several witnesses about a closet and a so-called "hidden room" inside former President Donald Trump's residence at Mar-a-Lago that the FBI didn't check while searching the estate in August 2022, sources familiar with the matter told ABC News.
As described to ABC News, the line of questioning in several interviews ahead of Trump's indictment last year on classified document charges suggests that -- long after the FBI seized dozens of boxes and more than 100 documents marked classified from Trump's Mar-a-Lago estate -- Smith's team was trying to determine if there might still be more classified documents there.
According to sources, some investigators involved in the case came to later believe that the closet, which was locked on the day of the search, should have been opened and checked.
As investigators would later learn, Trump allegedly had the closet's lock changed while his attorney was in Mar-a-Lago's basement, searching for classified documents in a storage room that he was told would have all such documents. Trump's alleged efforts to conceal classified documents from both the FBI and his own attorney are a key part of Smith's indictment against Trump in Florida.
Jordan Strauss, a former federal prosecutor and former national security official in the Justice Department, called the FBI's alleged failure to search the closet "a bit astonishing."
"You're searching a former president's house. You [should] get it right the first time," Strauss told ABC News.
In addition to the closet, the FBI also didn't search what authorities have called a "hidden room" connected to Trump's bedroom, sources said.
Smith's investigators were later told that, in the days right after the search, some of Trump's employees heard that the FBI had missed at least one room at Mar-a-Lago, the sources said.
According to a senior FBI official, agents focused on areas they believed might have government documents.
“Based on information gathered throughout the course of the investigation, areas were identified and searched pursuant to the search warrant,” the official told ABC News.
Within a few months of the FBI's search, federal prosecutors in the Justice Department pushed Trump's legal team to ensure that no classified documents remained at any of Trump's properties, but it's unclear if those prosecutors or any Trump lawyers even knew about the unexamined spaces then.
It's also unclear if Trump ever kept any classified documents in either of those spaces, or whether Smith's team ever considered seeking another warrant to search Mar-a-Lago again.
In their questioning of witnesses, Smith's team seemed to focus more on the missed spaces in the three months before first indicting Trump in the case, sources said.
