Mavis Nicholson Leno is the Chair of the Feminist Majority Foundation's Campaign to Stop Gender Apartheid in Afghanistan, and has been the United States' most outspoken critic of the Taliban's horrific treatment of women.

Leno joined the Board of Directors of the Feminist Majority Foundation in 1997, after playing an active role in the effort to defeat Proposition 209, the anti-affirmative action initiative on the 1996 California ballot.

Leno assumed her role as Chair of the Campaign to Stop Gender Apartheid in Afghanistan in 1997 less than one year after the Taliban's brutal treatment of women began.

She testified on gender apartheid in March 1998, before Senator Dianne Feinstein of the U.S. Senate Foreign Relations Committee, and has consistently urged the Clinton and Bush Administrations, as well as the U.S. Congress, to do more to restore women's human rights in Afghanistan.

Her involvement in the Feminist Majority's Campaign was also instrumental in defeating the energy company UNOCAL's efforts to construct an oil pipeline across Afghanistan that would have supplied the Taliban with over $100 million and dramatically increased their control in the region.

She is currently a leader in the effort to make the restoration of women's rights a nonnegotiable element of a post-Taliban Afghanistan.
