Dr. Stein made it official Monday on Twitter, saying she was "Honored to announce human rights champion Ajamu Baraka as my VP running mate!"

On Baraka's personal website, he is described as having "roots" in "the Black Liberation Movement and anti-apartheid and Central American solidarity struggles." He was, until 2011, the Founding Executive Director of the US Human Rights Network. His work has been primarily in the humanitarian sector, and he has partnered with Amnesty International in the past. He is an Associate Fellow at the Institute for Policy Studies in Washington, DC.

History requires that I now start twitting, so forgive my tardiness and stay close to me over the next three month #SteinBaraka#VoteGreen — Ajamu Baraka (@ajamubaraka) August 2, 2016

Stein has been seeking to court jaded supporters of Bernie Sanders, who lost the Democratic Party's nomination to former Secretary of State Hillary Clinton.
