Donald Trump pleaded not guilty at an arraignment in Miami on Tuesday to 37 charges of mishandling classified information, an indictment that made him the first former United States president to be federally prosecuted.
On Friday, the US Justice Department unsealed an indictment that outlined 37 criminal charges against Trump, including 31 under the Espionage Act.
Other charges include conspiracy to commit obstruction and false statements, Al Jazeera reports.
Trump stands accused of unlawfully hoarding dozens of sensitive national security files in his Mar-a-Lago estate in Florida when he left office in 2021. He later refused to return them and conspired to obstruct the investigation to retrieve them.
He is also charged with sharing sensitive US secrets with people who had no security clearance.
The material he stored in his home included nuclear programmes, defence and weapons capabilities of the US and foreign governments, the indictment said.
