The large scale solidarity movement comes less than 24-hours after the inauguration of President Donald Trump, but several march organizers insist the march is not an anti-Trump march – it is a march on rights, especially women’s rights.

Organizers said the women’s march is meant to show global support for women’s rights, human rights and social justice.

And on Saturday morning, the people pouring into Washington D.C. to fight for those rights.

Hundreds carried signs throughout the march reading…

We demand ethical leadership,

Keep your rosaries, off my ovaries,

Keep your laws off my body,

Don’t normalize, don’t rationalize, don’t close your eyes – Stand Up! Stay Strong! Resist!

The rights should never stop coming!

Men of quality do not fear equality!

The march on Washington was said to have a crowd of 600,000.

Shortly before 1 p.m., officials said people were standing along the entire march route.

The crowd is still expected to march toward the Ellipse, an area of the National Mall in front of the White House, though no formal march will be led.
