Former President Donald Trump pleaded not guilty on Thursday to charges related to efforts by him and his 18 co-defendants to overturn the 2020 presidential election.

According to a filing released by Trump and his attorney, Steven Sadow, the former president stated that he pleaded not guilty to the charges and waived his right to be present at his formal arraignment. Trump identified himself in the filing as president despite not holding the title since losing the 2020 election.

Trump turned himself in at Atlanta’s Fulton County Jail on Aug. 24 after District Attorney Fani Willis set an Aug. 25 deadline for all co-defendants to surrender to authorities. The indictment handed by Willis’ office accuses Trump and his allies of carrying a broad “criminal enterprise” meant to overturn Georgia’s 2020 election results and keep Trump in power. Among the charges Trump faces include racketeering and forgery.
