If you have visited Facebook or Twitter over the last 24 hours, two words have taken over social media feeds: "Me too."

Users are posting tweets or status updates with the phrase to demonstrate how many people have been impacted by sexual harassment or abuse.

The campaign started Sunday on Twitter, through a tweet by actress Alyssa Milano, in response to multiple women accusing Hollywood producer Harvey Weinstein of sexual misconduct.

Since then, countless people — both men and women — have come forward sharing the phrase, as well as their stories about sexual harassment or assault.

On Saturday, Weinstein was expelled by the Academy of Motion Picture Arts and Sciences board following a series of reports detailing allegations of sexual misconduct against the producer. Weinstein denies the allegations.
