POLITICO reports that Senator Elizabeth Warren, who legally became a candidate when she registered a candidate campaign committee with the Federal Election Commission on January 31, "is expected to formally announce her plans to run for president" on February 9.
In a message posted Thursday evening on Instagram, Facebook and Twitter, the Massachusetts Democrat told supporters to expect a major announcement on Feb. 9.
“One month ago today, we launched this presidential exploratory committee to build a grassroots movement to level the playing field for working people,” she wrote. “Since then, we’ve traveled to Iowa, New Hampshire, South Carolina, Puerto Rico, & heard from thousands of people all across the country. I’ll be making a BIG announcement about my 2020 plans on Saturday, February 9.”
