Former President Donald Trump has pleaded not guilty to three new charges related to his handling of US classified documents after he left the White House in 2021, a court filing showed.
Mr Trump, the front-runner for the 2024 Republican presidential nomination, also waived his right to be present in Florida federal court for his arraignment on the three additional charges on 10 August.
Mr Trump now faces 40 charges in the documents case after originally being indicted on 37 counts last month.
His valet, Walt Nauta, is also facing new charges, and prosecutors added a third defendant and another Trump employee, Carlos De Oliveira, to the case in a superseding indictment last week.
It was unclear whether Mr Nauta and Mr De Oliveira would be present in court to enter their pleas on 10 August.
Their lawyers did not immediately respond to requests for comment.
Prosecutors accused Mr Trump of taking hundreds of documents containing the nation's most closely-held secrets - including details about the US nuclear programme and military plans - and storing them haphazardly at his Mar-a-Lago estate in Palm Beach, Florida.
Mr Trump also showed classified information to people who were not authorised to see it, according to the indictment.
Mr Nauta and Mr De Oliveira, a property manager at Mar-a-Lago, are accused of trying to hide the documents from federal investigators seeking their return and attempting to destroy evidence, including security camera footage.
Mr Trump in April became the first sitting or former US president to face criminal charges when he was indicted in New York state court, accused of falsifying business records to conceal hush money payments to an adult film star. He pleaded not guilty.
He was indicted for the third time on Tuesday in Washington federal court regarding his efforts to overturn his 2020 presidential election loss.
That case and the documents case are being pursued by Special Counsel Jack Smith.
Prosecutors in Fulton County, Georgia are also probing Trump's efforts to reverse his 2020 election loss in that state and are expected to announce a charging decision by 18 August.
