Former President Donald Trump’s lawyers have acknowledged the possibility that he could be indicted as the investigation into his retention of top secret government documents at his Mar-a-Lago resort in Florida continues.

Trump had recently claimed that he couldn’t imagine being charged. But his lawyers made the admission that he could be indicted in a court filing on Monday. They proposed how to conduct an outside review of documents that were seized by the Federal Bureau of Investigation (FBI) in August.

A special master, federal judge Raymond Dearie, had previously asked the former President to share details of any materials that were stored at Mar-a-Lago that he might have decided to declassify, reported The Guardian. In the court filing, Trump’s lawyers said that requiring the special master to do so could hurt any possible defense should he later be charged. They said that Trump should not have to “fully and specifically disclose a defense to the merits of any subsequent indictment without such a requirement being evident” during the review.

Dearie was scheduled to have his first meeting with Trump’s attorneys and their opponents in the case -- the U.S. Department Of Justice (DOJ) prosecutors, on Tuesday in federal court in Brooklyn. The special master is said to have turned down Trump side’s request to delay asserting what materials he might have classified.

So far, Trump has been reluctant to publicly consider the possibility that he could be criminally charged after the FBI’s August search. In a recent interview Trump said that he can’t imagine "being indicted, I’ve done nothing wrong." He was referring to the classified documents case and the investigation into his efforts to undermine the results of the 2020 Presidential election.

Meanwhile, his lawyers urged a federal appeals court on Tuesday to reject a DOJ bid to resume its review of documents marked classified that were seized from his home, reported CNBC. The filing in the U.S. Court of Appeals for the 11th Circuit came just hours before Trump's lawyers and the DOJ were set to appear in federal court in Brooklyn. The purpose of the meeting was to speak with the special master who was appointed to examine the records that were seized from Mar-a-Lago.
