Racist tweet about Michelle Obama sparks outrage

A racist post about US First Lady Michelle Obama has prompted calls for the director of a West Virginia development group and a mayor to be sacked.

Clay County Development director Pamela Ramsey Taylor made the post following Donald Trump's election as president, saying: "It will be refreshing to have a classy, beautiful, dignified First Lady in the White House. I'm tired of seeing a Ape in heels."
