Vermont Sen. Bernie Sanders, Biden’s sole staying challenger, left of the primary race last week and backed the previous vice president on Monday.
Warren followed suit Wednesday, officially tossing her support behind Biden after declining to endorse either him or Sanders in the last weeks of the primary.
Along with Sens. Kamala Harris of California and Amy Klobuchar of Minnesota, Warren is one of 3 former Democratic White Home hopefuls Biden is reportedly considering inviting onto the ticket.
But Warren’s clashes with Sanders during the main have actually left unsolved bitterness among some in the party’s left flank, suggesting that giving her the vice presidential nod may not be a cure-all in terms of party unity.
Biden has already dedicated to choosing a female running mate, and has revealed openness to presenting a woman of color for the position.
Apart from Biden’s former rivals, political leaders often mentioned as possible vice governmental picks include Michigan Gov. Gretchen Whitmer, former Georgia gubernatorial candidate Stacey Abrams, Florida Rep. Val Demings, Wisconsin Sen. Tammy Baldwin, New Mexico Gov. Michelle Lujan Grisham, Nevada Sen. Catherine Cortez Masto, Illinois Sen. Tammy Duckworth and others.
In July, Warren confirmed she would have accepted an offer from previous Democratic presidential nominee Hillary Clinton to become her running mate during the 2016 campaign, after a report exposed Warren had actually received a “complete vetting” for the role by Clinton’s group and was interviewed at the prospect’s Whitehaven estate in Washington.
