After the initial flurry of excitement, followed by fears about a lack of permits and organizational experience, the Women’s March on Washington is firming up with a planned starting location and new, high-profile help.

Organizers announced today that Planned Parenthood is joining as a “key partner” and Gloria Steinem and Harry Belafonte will serve as honorary co-chairs.

“This is an historic moment to come together to protect the progress we’ve made,” Planned Parenthood president Cecile Richards said in a statement. “We will send a strong message to the incoming administration that millions of people across this country are prepared to fight attacks on reproductive health care, abortion services, and access to Planned Parenthood, as they intersect with the rights of young people, people of color, immigrants, and people of all faiths, backgrounds, and incomes.”

The march stumbled out of the chaos of the first few days after the election. Several people independently came up with the idea, and then banded together to make it a reality. “We had no idea how quickly this was going to snowball,” Bob Bland told DCist at the time.

Snowball it did, with hundreds of thousands of people indicating that they planned on attending. The group quickly ran into a wall of logistics issues and other criticisms, including over the name (it was originally billed as the Million Woman March on Washington). Several veteran organizers stepped in to lead the ship.

Planned Parenthood will now add their expertise too, helping with staffing, planning efforts, and safety plans. Feminist icon Gloria Steinem and singer and activist Harry Belafonte will lend additional gravitas.

“We know that we stand on the shoulders of giants, and we are thrilled to welcome Ms. Steinem and Mr. Belafonte as honorary co-chairs,” said co-chair Linda Sarsour. “Alongside our new partner Planned Parenthood, together we are bridging the historical struggles for women’s rights and civil rights to the current intersectional movement for dignity and human rights.”

Organizers originally planned to gather at the iconic Lincoln Memorial only to learn later that the National Park Service gives first priority for the site to the Presidential Inaugural Committee. They worked with NPS on an alternate plan, announcing last month that the march will start the march at Independence Avenue and Third Street SW, near the U.S. Capitol, at 10 a.m. on January 21, 2017. The full route has not yet been determined.
