More than two dozen women, including actresses Angelina Jolie and Gwyneth Paltrow, have made allegations against him.
Police forces in the US and the UK are investigating these allegations.
Weinstein has insisted through a spokesperson that any sexual contacts he had were consensual, and he denies accusations of criminal sexual harassment, rape and sexual assault.
