Female co-anchors of disgraced CBS host Charlie Rose speak out on-air

Veteran news anchor Charlie Rose has been fired from American TV network CBS, following allegations of sexual misconduct.

His co-hosts addressed the allegations on air Wednesday morning (US time), saying there was "no excuse" for their co-host's alleged behaviour. 

"This is a moment that demands a frank and honest assessment of where we stand and, more generally, the safety of women," Norah O'Donnell said. "Let me be very clear - there is no excuse for this alleged behaviour. 

"It is systematic and it is pervasive."

Gayle King described "struggling" with the news.

"I've held him in such high regard and I'm really struggling, because... what do you say when someone that you deeply care about has done something that is so horrible?" 

The allegations against Charlie Rose were first brought to light in a Washington Post article, published Monday.

He is accused of acts that include unwanted sexual advances, groping and exposing himself. 

Charlie Rose's firing continues the wave of high-profile men accused of sexual misconduct, including Harvey Weinstein, Louis CK and Kevin Spacey.
