A day after the fourth Democratic presidential debate and following reports that Vermont Sen. Bernie Sanders could pick up endorsements from three progressive congresswomen, U.S. Rep Ayanna Pressley of Massachusetts held off from backing any candidate.

The Washington Post and others reported that freshman Reps. Ilhan Omar of Minnesota and Alexandria Ocasio-Cortez of New York said they would support Sanders, who has consistently polled in third place behind former Vice President Joe Biden and Massachusetts Sen. Elizabeth Warren.

Democrats throughout Tuesday night’s debate hammered Warren, who has risen and even overtaken Biden in some recent polls. Pressley and Warren have supported each other on multiple policies and partnered to push for a national real-time payments system.

But Pressley said through a spokesman that endorsements are ultimately decisions “made as individuals.”

“Ayanna has tremendous respect for her sisters-in-service,” said spokesman Harry Shipps, referencing the other congresswomen. “Ayanna knows that taking back the White House in 2020 is a top priority, and she is working every day to hold this administration accountable and build a bold, diverse movement that will help propel Democrats to victory up and down the ballot.”

Multiple outlets reported that U.S. Rep. Rashida Tlaib of Michigan also planned to back Sanders. But she told the Detroit Free Press on Wednesday that she had not made any endorsements, nor planned to appear at a Sanders rally in New York City this weekend. During the debate, Sanders noted his rally would feature “a special guest,” and Ocasio-Cortez later said she would appear with him.

Pressley, Tlaib, Omar and Ocasio-Cortez, all first-time progressive congresswomen of color under the age of 50, are often described as “The Squad.”

Pressley has also decided to remain neutral on the Democratic primary race pitting U.S. Rep. Joe Kennedy III against incumbent Massachusetts Sen. Ed Markey.

“Congresswoman Pressley has enjoyed a great working relationship with both Sen. Markey and Rep. Kennedy, and has deep respect for their committed advocacy,” she said in a recent statement. “She remains focused on working on behalf of the people of the 7th congressional district and making progress on key issues like gun violence and trauma, health care and housing.”
