Gloria Steinem will help lead a march in Washington, D.C. after Donald Trump's inauguration as president, she announced on Instagram Tuesday.
The Women's March on Washington also includes entertainer and civil rights activist Harry Belafonte and partners with Planned Parenthood, BuzzFeed News reported. The organizers said on the event's website that the march was created to "send a bold message to our new government on their first day in office, and to the world that women's rights are human rights."
Steinem, a journalist and longtime feminist activist who launched Ms. Magazine in the 1970s, threw her support behind the effort as an honorary co-chair on social media.
Steinem supported Democratic presidential nominee Hillary Clinton during the campaign and came under fire when she suggested that young women who supported Clinton's challenger, U.S. Sen. Bernie Sanders, only did so to attract men, The Hill reported. She later apologized for the comment.
March organizers told BuzzFeed that the event was more "pro-women rather than anti-Trump" and called it "a display of solidarity affirming our shared humanity and fundamental human rights."
Event co-chairs include Tamika Mallory, a former executive director of the National Action Network; Linda Sarsour, an executive director of the Arab American Association of New York; Carmen Perez, an executive director of The Gathering for Justice; and Bob Bland, CEO and founder of Manufacture New York, BuzzFeed said.
"This is an historic moment to come together to protect the progress we've made," Planned Parenthood president Cecile Richards said in a statement, according to the website the DCist.com.
"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," she continued.
Organizers told The Washington Post earlier this month that the march will start at Independence Avenue and Third Street SW, in front of the Capitol.
