Saad Ibrahim Almadi, a 72-year-old dual U.S.-Saudi national and retired project manager, has been released from prison in Saudi Arabia after more than a year of imprisonment for tweets critical of the Saudi crown prince. His son, Ibrahim Almadi, has expressed concern for his father's health and hopes he will be able to return home to Florida soon. The case has highlighted the kingdom's strict laws on freedom of expression, which have been criticized by human rights groups.
