Sen. Elizabeth Warren (D-Mass.) revealed on Monday that she has formed an exploratory committee to run for president in 2020, and aims to officially declare her bid for the Democratic nomination in early 2019. 

Warren made the announcement in a video she posted to Twitter, where she shared her ideals: “no matter what our differences, most of us want the same thing: To be able to work hard, play by the same set of rules, and take care of the people we love.”

Warren underlined the type of campaign she is determined to run. In it, she labels Washington as a “whole scam” for the “wealthy and well-connected,” and defines Fox News as an “echo chamber of fear and hate.” It shows images of Fox News personalities  Sean Hannity, Laura Ingraham, Tucker Carlson, and the hosts of Fox and Friends, as well as players from the Trump administration.

Warren’s campaign will be one of many vying for the Democratic nomination, which could be as high as two dozen, Variety reports. From the video, it looks like Warren will attempt to appeal to the left of the Democratic party, and has expressed her readiness to take Wall Street and big banks head-on. 

“Our government is supposed to work for all of us, but instead it has become a tool for the wealthy and well-connected,” Warren said. “The whole scam is propped up by an echo chamber of fear and hate, designed to distract and divide us. People will do or say anything to hang on to power, point the finger at anyone who thinks, prays, or loves differently than they do.”

Warren began her career as an academic and consumer advocate and found the spotlight during the 2008 financial crisis when she chaired a congressional panel to supervise the bank bailout. Later, she accepted a role in the Obama administration and was part of the formation of the Consumer Financial Protection Bureau. She ran for Senate in 2012 and won against the incumbent, Scott Brown.
