A prominent activist and professor of African American history at George Washington University has admitted that she has been pretending to be a black woman.

Jessica Krug, 38, wrote on the blog website Medium that her various identities have been built on a "toxic soil of lies" and she is in fact a white Jewish woman from Kansas City.

The revelation draws parallels with the case of former civil rights activist Rachel Dolezal, who was exposed by her parents in 2015 to have been lying about being black.
