A Senate committee voted to advance the nomination of Betsy DeVos as secretary of education Tuesday.

The vote was split along party lines, with all 11 Democrats on the Senate Health, Education, Labor and Pensions Committee voting to reject DeVos, and all 12 of the committee’s Republicans voting to approve her. Next, DeVos faces a full Senate vote. Two Republican senators on the HELP Committee, Susan Collins (Maine) and Lisa Murkowski (Alaska), suggested that they were not sure how they would vote at that point.

“I have not been persuaded that Betsy DeVos will put students first if she were confirmed and I have not been persuaded that she has the experience, skills, understanding or vision to lead this critical department at a time when it is more important than ever,” committee ranking member Patty Murray (D-Wash.) said Tuesday before the vote. “There is so much about Betsy DeVos’ record over the years that we can look to when we make this decision.”

DeVos has inspired staunch opposition from some Democratic lawmakers and progressive groups. Although her vote in committee was originally scheduled for last week, it was delayed so lawmakers would have more time to review the paperwork she filed with the Office of Government Ethics. DeVos answered questions during a committee hearing earlier this month, but in the past week, Democrats requested a second opportunity to question her amid new revelations about her vast financial entanglements. Their request was rejected.

Since DeVos’ hearing, Democrats submitted over 800 additional written questions to the nominee in an effort to get more details on her views. By Monday evening, DeVos had responded to all of the questions, but some Democrats complained that her answers were not sufficient and actually raised more questions. On Monday afternoon, Murray once again pressed for a postponement of the vote.

“After an initial review of the responses sent to Committee members with less than twenty four hours before the scheduled vote, staff has identified a number of critical questions about Ms. DeVos’ financial disclosure to the Committee and other areas that have not been answered to anywhere close to satisfaction,” said a Monday statement from Murray’s spokesperson, Eli Zupnick. “Senator Murray does not believe that members of the Committee have enough information about Ms. DeVos’ opaque finances, conflicts of interest, and other issues.”

DeVos, a Michigan native, comes from a billionaire family that has donated millions of dollars to members of Congress. She is a passionate education activist, mostly involved in causes that prop up private and charter schools. Her opponents say that her interest in these institutions comes at the expense of traditional public schools ― which a vast majority of American students attend ― and that her views could have disastrous consequences for the public school system.

DeVos has never formally worked in a public school. She is a staunch opponent of teachers unions, and a broad coalition of civil rights groups also say they are worried about her ascent. On Monday, about 250 national and local civil rights groups signed an anti-DeVos letter, saying that she “has demonstrated no previous commitment to ensuring equal educational opportunity in school.”

In recent weeks, the chorus of voices challenging DeVos appears to have grown louder. After putting up what many saw as a lackluster performance at her confirmation hearing, protests opposing her confirmation broke out across the nation. During the hearing, DeVos stumbled over key questions and became fodder for late-night television after saying that schools might need guns to protect against grizzly bears. A review of written answers she submitted to the committee showed many lines were lifted verbatim and without citation from statutes and other sources.

Several Democratic lawmakers report having seen an influx of anti-DeVos calls from constituents, and some have even begun capitalizing on the fierce opposition to her as a fundraising tactic, reports Education Week. The progressive change network CREDO Action collected over 1.4 million signatures on an anti-DeVos petition, a record for the group.

Still, she has strong support from prominent Republicans such as HELP Committee Chairman Lamar Alexander (Tenn.), former Florida Gov. Jeb Bush and 2012 Republican presidential nominee Mitt Romney. Before the vote, Alexander noted that he thinks DeVos has been the most questioned education secretary nominee in history.

“I don’t think it’s fair to treat Ms. DeVos so different than we did Obama’s nominees,” Alexander said. “I respect my colleagues, I don’t question their motives, I don’t question their votes, but I believe their concerns are misplaced.”

Also during Tuesday’s HELP Committee panel, Murray called for a vote on an amendment that would require Cabinet nominees to release their tax returns.

“I have asked each Cabinet-level nominee that this committee will consider to submit three years of tax returns ― but so far each has refused,” she said. “So I am hopeful we can come together, across party lines, in the interest of good government and ethics ― and pass this amendment to move the HELP Committee to where a number of other committees already are, including Finance, Budget, and Homeland Security and Governmental Affairs.”

The amendment was defeated along party lines.
