About two million people are thought to have marched across the world in protest of Donald Trump becoming America's 45th President.
And more than one million people marched in Washington DC alone, more than the total live audience who watched President Trump sworn in.
But in a blistering attack on the protesters and celebrities who spoke out, Mr Trump tweeted: "Watched protests yesterday but was under the impression that we just had an election! Why didn't these people vote? Celebs hurt cause badly."

A number of celebrities joined protestors in the US capital on Saturday, incuding actresses America Ferrera, Ashley Judd and Scarlett Johansson.
But it was pop star Madonna who caused the most consternation amongst Trump supporters, after she claimed to have tought about "blowing up the White House" during a profanity-strewn speech.
The singer said: "Good didn’t win this election, but good will win in the end. So what today means is that we are far from the end. Today marks the beginning of our story.
"The revolution starts here. The fight for the right to be free, to be who we are, to be equal. Let’s march together through this darkness and with each step know that we are not afraid, that we are not alone, that we will not back down."
