From the New York Times, I'm Michael Barbaro. This is Daily.

Today, after the divisiveness of the 2016 election, the women's march became a historic symbol of unity.

Two years later, a rift has formed.

It's Friday, January 18th.

Ferris Stockman, how did the women's march start?

So it started with an idea floated on Facebook by a woman in Hawaii who just said,

we ought to have a big march against Trump and it went viral. And a group of women in New York City wanted to turn that idea into a reality.

And one of the first central organizers was a white Jewish woman named Vanessa Rubel.

And she asked around and said, we need women of color.

She asked some friends, do you know any women who would be good at helping to plan this march?

And she got given the name of Tamika Mallory, who was a black gun control activist,

and Carmen Perez, a criminal justice reform activist.

And they all sat down together and started planning the march.

Well, more than 160,000 people are committed now to what's expected to be the largest demonstration in response to Donald Trump's inauguration.

Organizers of the women's march on Washington, which is set for the day after the inauguration,

they say it's unclear just how big the march is going to get. So the march was huge.

In the nation's capital, hundreds of thousands turned out for the women's march on Washington.

Organizers estimate that over four million more rallied against the Trump administration in some 670 sister marches

in cities across the country and around the world.

It was way bigger than the inauguration.

Beyond their wildest dreams, some of the organizers of the women's march telling me here tonight,

they had no idea the country would respond like this.
