BUENOS AIRES, Argentina (AP) — A tribunal in Argentina on Wednesday upheld a six-year prison sentence and a lifetime ban from holding public office against former President Cristina Fernández, a dominant political leader in recent years in the South American country. Fernández was convicted and sentenced in 2022 by a three-judge panel for a fraud scheme that embezzled millions of dollars through public works projects during her presidency. She appealed, but the higher tribunal ratified the original ruling.
