CNN reports that on New Year's Eve 2018, Senator Elizabeth Warren announced her formation of an "exploratory committee" for the 2020 presidential election. "Exploratory committee" is not an actual committee type under federal campaign finance law--Warren actually registered a 2020 presidential campaign committee with the FEC. Regardless of whether Warren has yet made up her mind to run for president in 2020, she will be complying with candidate contribution limits and disclosure requirements from December 21, 2018 onward.
Massachusetts Sen. Elizabeth Warren took a major step toward a presidential run on Monday, announcing in a video message and email to supporters that she is forming an exploratory committee ahead of an expected campaign for the Democratic nomination in 2020.
With her announcement 13 months before the Iowa caucuses, Warren, who became a progressive star by taking on Wall Street after the 2007 financial crisis and, more recently, President Donald Trump, is the first Democrat with a national profile to take formal action ahead of an anticipated presidential campaign.
