Carmen Ejogo and Susan Sarandon are the latest celebrities to add their voice to LGBT advocacy group Lambda Legal‘s campaign for marriage equality.

Ejogo, who starred as Coretta Scott King in “Selma,” said in a video for the group’s #IDo campaign that her support for LGBT rights traces its roots in her Nigerian-Scottish heritage.

“I haven’t fully [fit] into the black community, the white community, I’ve had to sort of find my space. And I think for that reason I have a lot of empathy for anyone that’s going through the same kind of desire for identity approval in the mainstream,” she said. “If we do the right thing in terms of marriage equality, there may be other nations that could follow suit. And that’s for the betterment of all of us.”

Last month, Julianne Moore recorded a video for the campaign detailing the reasons why the fight for LGBT rights doesn’t end with marriage equality.

Lambda Legal’s board co-chair, Karen Dixon, blogged for HuffPost earlier this year announcing that she and her wife, Nan Schaffer, would match up to $1 million in donations to the #IDo campaign. The organization announced Thursday that it had met the $1 million mark.
