Morgan's jokes cause new offence
Tracy Morgan had just finished apologising for his anti-gay jokes, and now the comedian is in hot water again.
In his stand-up act in New York last weekend, the 30 Rock star mocked the disabled and people with learning difficulties, according to The New York Times.
This has led to a demand for an apology from Morgan by a US group promoting the rights of the mentally and physically disabled.
His wisecracks reportedly included a warning not to "mess with women who have retarded kids".
His remarks are "far too offensive to be excused as comedy," Peter Berns, head of The Arc, said. He called for an immediate apology.
So far, Morgan has offered no response.
Earlier this month, he apologised for a homophobic rant made during a stand-up routine in Nashville.
