Sen. Elizabeth Warren is planning to drop out of the 2020 Democratic primary, The New York Times first reported Thursday. Her withdrawal narrows the contest to the two frontrunners, former Vice President Joe Biden and Sen. Bernie Sanders, and Tulsi Gabbard.

Warren has notoriously skewered her wealthy opponents.

She went after former New York City Mayor Michael Bloomberg in one debate saying: "Democrats take a huge risk if we just substitute one arrogant billionaire for another." In another debate, she criticized former Mayor Pete Buttigieg for hosting a donor dinner "held in a wine cave full of crystals and $900-a-bottle wine."

"We made the decision many years ago that rich people in smoke-filled rooms would not pick the next president of the United States," Warren said at the time. "Billionaires in wine caves should not pick the next president of the United States."

While Warren is not a billionaire, when Bloomberg ended his bid for the nomination on Wednesday morning, it briefly rendered Warren the richest remaining Democratic presidential nominee hopeful.

Warren and her husband have an estimated combined net worth of $12 million, according to Forbes. Most of their wealth is held in retirement accounts and real estate. The senator has also brought in hundreds of thousands from book royalties.

A spokesperson for Warren didn't immediately respond to a request for comment from Business Insider.
