Time's Up insists that R. Kelly, who's been at the center of sexual misconduct allegations for 25 years, has overstayed his welcome.

In a letter posted to The Root Monday (April 30), the group's Women of Color subset very vocally supported a new campaign called #MuteRKelly, and said while comedian Bill Cosby's recent sexual assault convictions were horrific, they served as cement proof that men can, indeed, be held accountable for their crimes against women.

The group claims R. Kelly "Married a girl under 18 years of age; was sued by at least four women for sexual misconduct, statutory rape, aggravated assault, unlawful restraint and furnishing illegal drugs to a minor; was indicted on 21 counts of child pornography and has faced allegations of sexual abuse and imprisonment of women under threats of violence and familial harm."

Now, Time's Up is calling for RCA Records, Ticketmaster, Spotify, Apple Music and concert venues to ice Kelly out, and to make him pay for his transgressions.

"As women of color within Time’s Up, we recognize that we have a responsibility to help right this wrong. We intend to shine a bright light on our WOC sisters in need. It is our hope that we will never feel ignored or silenced ever again," the letter reads. "We call on people everywhere to join with us to insist on a world in which women of all kinds can pursue their dreams free from sexual assault, abuse and predatory behavior."

Time's Up's Women of Color aims to "organize around issues that are especially important to women and girls of color. The group includes activists, executives, filmmakers, actresses, authors, athletes, and women in tech, advertising, science and other industries. WOC of TU is building a collective of women of color who strive for safe and equitable environments for all women," the letter specifies.
