Piers is not impressed with Madge:
It's also being reported that there are too many people on the streets of Chicago for the march part of the protest to happen:
Organizers are giving out more instructions for the procession through Washington, also asking protesters to "please clean up the trash" before they go.
From RFE/RL's Washington correspondent Carl Schreck:
Here's a video of Norah Jones' appearance, which we mentioned earlier:
After getting the crowd to join them in chanting "The people united will not be defeated," march organizers have called on the protesters to march with them toward the Washington monument. Still no real sign of anyone leaving yet though.
A pretty feisty speech from Madonna:
Telling the crowd that she was there because the current milieu means that it's "not just women in danger, but all marginalized people," she also told the protesters that the gathering had shown "that we are not afraid, that we are not alone, and that we will not back down; that there is power in our unity and that no opposing force stands a chance in the face of true solidarity."
She also took a swipe at "detractors that insist that this march will never add up to anything ("F*** you! F*** You!").
And she warned protesters that the journey ahead would be hard, but that this was the "hallmark of revolution"
"Yes, I am angry," she said. "Yes, I am outraged and thought an awful lot about blowing up the White House, but this won't change [anything]."
She then quoted WH Auden's famous poem September 1, 1939 -- "We must love one another or die" -- before launching into a feisty rendition of Express Yourself and an expletive-laced version of Human Nature (I'm Not Your B****), which she dedicated to Donald Trump.
Bit of a buzz of excitement now, as Amy Schumer has just introduced Madonna to the crowd...
Pretty big crowd in New York City by the looks of things:
