Massachusetts Democratic Rep. Ayanna Pressley on Wednesday announced her endorsement of Sen. Elizabeth Warren, D-Mass., for president. Pressley made the announcement in a one-minute video, drawing on her ties to her home-state senator. “I’m proud to call her my senator,” she says. “I can’t wait to call her our president.” Pressley is the last member of the so-called Squad to weigh in on the 2020 presidential race. Reps. Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, and Rashida Tlaib of Michigan all endorsed Sen. Bernie Sanders, I-Vt., last month. Warren is “fighting for fundamental change that restores power to those who have been left behind, and centers those who have never had access to it in the first place,” Pressley says in the video. “She is consistent. She never loses sight of the people.”

In a statement, Pressley lauded Warren’s work to empower working people: “From fighting to erase income inequality and close the racial wealth gap, to taking on the epidemic of gun violence and working to dismantle structural racism, Elizabeth has made it her life’s work to pursue justice for working families and put economic and political power in the hands of people.” Pressley’s split with the rest of the Squad over the presidential endorsement will be seen by some on the left as further proof that she’s relatively more moderate than her fellow progressive first-term representatives. In 2016, she was a surrogate for former Secretary of State Hillary Clinton in her primary battle against Sanders. During her congressional campaign last year and since entering office, Pressley has supported policies that have come to represent something of a litmus test for the left, like abolishing U.S. Immigration and Customs Enforcement and supporting Medicare for All and debt-free college. As The Intercept reported during the campaign, she’s moved further left since her time in Boston politics on issues like corporate money in politics and the advisability of Medicare for All.

Still, in Congress, she’s faced criticism over breaking with progressive members and voting for a resolution that condemned the Boycott, Divestment, and Sanctions movement. California Rep. Ro Khanna, a campaign co-chair for Sanders, also voted for that measure. These differences are particularly noteworthy, critics say, because Pressley’s district leans more heavily blue than those of Omar, Ocasio-Cortez, or Tlaib, who each represent districts that voted for Donald Trump at higher percentages than Pressley’s.
