He has been under house arrest for over 500 days. Will Menaker recently did an interview with him explaining how he was persecuted by the judicial system for winning a court case against a corporation. Here is where to watch: https://ww2.ca2.uscourts.gov/court.html
edit: Donziger's trial started at 10:41 central.
edit: The hearing is over, I'm not sure when the judge will rule.
I think it went well. Hopefully Donziger will be freed. Keep in mind the fight to help the Indigenous Ecuadorians will still be ongoing after today. Chevron still claims that the Ecuadorian court was corrupt and will continue to ignore the billions they owe.
I am sure Donziger will keep up the good fight. It is possible he may face further persecution for future activities.
