A day after President Donald Trump's inauguration, hundreds of thousands of people protested in Manhattan at the Women's March on NYC.

The march is the third day of demonstrations in New York City targeting Trump and his planned policies.

On Friday, just hours after Trump was inaugurated, protesters gathered at Foley Square in Manhattan.

Alec Baldwin, Marc Ruffalo and more celebrities, as well as Mayor Bill de Blasio and other politicians, joined thousands of New Yorkers outside Trump International Hotel and Tower on Thursday to voice their opposition to Trump.
