WATCH | Watch as Hollywood actors, musicians and politicians gathered in New York City Thursday to begin of 100 days of resistance against Trump.
Now that Donald Trump has taken the oath of office, don't expect protests to just fade away.
Critics who see his policies as attacks on issues like healthcare, immigrant rights and action on climate change are mobilizing for what they're calling 100 Days of Resistance.
Created by the Occupy Movement and led by director Michael Moore, the effort is trying to rally the help of artists, actors, and comedians to show up events that will take place around the country from Jan. 21 to April 29.
Gathering in front of New York's Trump International Hotel, Moore, Mark Ruffalo, and Cher on Thursday criticized Trump's first 100 day agenda that includes repealing environmental regulations, Obamacare, and the Dodd-Frank Act, which would give corporations a tax cut.
Twitter quickly picked up the message as the slogan was posted by hundreds of users.
These protests are part of several planned actions around the country in response to Trump's presidency.
During the inauguration celebrations, protestors clashed with police and set a vehicle on fire in front of The Washington Post headquarters in downtown D.C.
And there were other demonstrations planned in San Francisco, L.A. and Philadelphia, while students planned to walk out of colleges in Atlanta, Seattle and Austin, Texas, among other cities.
