A women's protest planned for the day after President-elect Trump's inauguration ceremony has a new, well-known activist leader: Gloria Steinem.

The nationally recognized feminist movement leader will be joining the "Women's March on Washington," which bills itself as a peaceful march following Trump's inauguration ceremony on Saturday, Jan. 21.

On Tuesday, Steinem, 83, said on her personal Instagram account that she will serve as an honorary co-chairwoman of the protest, alongside Harry Belafonte.

"Our communities are hurting and scared," the group's mission statement reads. "We are confronted with the question of how to move forward in the face of national and international concern and fear."

As of Wednesday afternoon, more than 156,000 had committed to the Facebook event.

The group says the protest will serve as a means to "stand together in solidarity" against "[t]he rhetoric of the past election cycle has insulted, demonized and threatened many of us."

Anti-Trump protesters are "acting unfairly," the president elect tweeted last month, dismissing criticism of controversial comments he said on the campaign trail.

A spokeswoman for the march pushed back against such claims, telling the Guardian that the march is "not targeting Trump specifically. It's much more about being proactive about women's rights."
