NATS: "Donald Trump has got to go" Two years after filling U.S. streets to protest the start of Donald Trump's presidency, women across the country marched again for a third time.

Their voices united for social justice and to build political pressure against Trump ahead of the 2020 elections.

NATS: RALLY The original Women's March group has splintered and spawned new organizations… with some leaders of the group having been accused of anti-Semitism, which they deny.

This year's movement saw alternate rallies being held as divisions have emerged.

SOUNDBITE: CO-ORGANIZER OF THE "MARCH FOR ALL WOMEN", PATRICE ONWUKA, SAYING: "Let's be clear.

Women are not a monolith.

We do not all think the same.

We do not all hold the same positions.

We don't all hold the same viewpoints.

And so it's fine in a free market system to have a competition of ideas and a competition of rallies." Despite the separate demonstrations, march leaders say momentum has not slowed, with hundreds of rallies held around the U.S. to celebrate unprecedented gains for women in recent congressional and state races.

SOUNDBITE: U.S. REPRESENTATIVE ALEXANDRIA OCASIO-CORTEZ, SAYING: "Last year we brought power to the polls... we have to make sure we transfer that power to policy." Policies like raising the minimum wage and making sure all women have access to healthcare, reproductive and voting rights.

Globally, marches were held in more than 30 countries to protest violence against women among other issues.

In central London, women took to the streets, calling for gender equality and equal representation in government.
