While promoting his new "Justice League" film, Affleck told The Associated Press that he is "looking at my own behavior and addressing that and making sure I'm part of the solution."
In an interview Sunday, Affleck said "more women need to be pushed to power" and that sexual harassment also has to be "a men's issue," saying that men should call out inappropriate behavior.
Last month, Affleck apologized for "acting inappropriately" toward actress Hilarie Burton more than a decade ago after Burton shared a video from "TRL Uncensored II" that featured her speaking to the actor and suggesting that he grabbed her breast.
"I acted inappropriately toward Ms. Burton and I sincerely apologize," he tweeted on Oct 11.
Weinstein has denied all accusations of non-consensual sex.
