According to sources, Weinstein is being treated for, according to reports, a form of blood cancer.
The former film producer has been struggling with health problems for a longer period and underwent heart surgery as recently as October.
The 72-year-old was sentenced to 23 years in prison in 2020 for rape and further assaults against two women in New York. However, this verdict was overturned earlier this year and will be retried, citing errors in the first trial. New charges will also be brought against Weinstein, who denies any wrongdoing in all cases.
In addition to the case in New York, he has also been sentenced to 16 years in prison by a court in Los Angeles.
The allegations against Harvey Weinstein surfaced in October 2017 and sparked the #metoo movement. In total, nearly 90 women have accused Harvey Weinstein of assault.
