Former US attorney general Bill Barr has spoken out against Donald Trump ahead of his court appearance for allegedly plotting to overturn his election defeat in 2020.
Mr Barr, who was appointed by the former president, said that Mr Trump "knew well he lost the election".
Mr Trump is accused by federal prosecutors of lying repeatedly about mass voter fraud and pressing officials to change results to keep him in power.
He will be formally charged later.
The 77-year-old Republican, who is running for election again, is expected to plead not guilty when he appears in court in Washington at 16:00 EDT (20:00 GMT). He has denounced the charges as politically motivated.
