Joan Rivers' daughter has accused Kathy Griffin of destroying her mother's legacy by replacing her on US TV show Fashion Police and quitting after less than two months on air.
Griffin joined the show in January to take over from regular host Rivers following her death last year .
But the comedienne's tenure did not last long and she exited in March after filming just seven episodes.
She announced her departure in a statement which appeared to criticise the premise of the show.
"My brand of humour, while unrepentant and unafraid, is all about context," she said.
