“CBS This Morning” anchors addressed the growing sexual abuse scandal involving their former boss Les Moonves on Monday, honoring the “courage” of the women who came forward with allegations against him.

“This is really hard. This is hard for everybody at CBS News, he is my boss, was my boss,” said one of the show’s co-hosts, Norah O’Donnell.

“It’s been another sleepless night thinking about this, the pain that women feel, the courage that it takes for women to come forward to talk about this,” she added.

O’Donnell, who became co-anchor of the morning show in 2012, said Moonves had always treated her “fairly and with respect” — but added that “there is no excuse for this alleged behavior.”

“It is systematic and it is pervasive in our culture,” she said. “Women cannot achieve equality in the workplace or society until there is a reckoning and a taking of responsibility.”

John Dickerson, another co-host, agreed with O’Donnell and commended her for her statement.

This is the second time in 10 months that O’Donnell has addressed allegations against someone at the network. She and co-host Gayle King spoke about sexual harassment allegations against their former co-host Charlie Rose in November.

“Gayle and I have talked and texted. And I said, ‘Gayle, I’m kind of looking back to November, when we dealt with accusations against our former co-host,’” O’Donnell said Monday. “And she said, ‘Yes, but I didn’t think we’d still be the story in September.’”

CBS confirmed on Sunday that Moonves was stepping down as CEO and chairman after being accused of sexual abuse or misconduct by a dozen women.
