Madonna spoke to the crowd -- estimated at over 500,000 people -- before performing at the march, held the day after President Donald Trump's inauguration.

"Yes, I have thought an awful lot about blowing up the White House. But I know that this won't change anything," the singer said.

A number of celebrities, including Michael Moore and Ashley Judd, and lawmakers participated in the march.

More than 600 women's marches took place Saturday in all 50 states and capital cities around the globe.
