U.S. Sen. Elizabeth Warren, who said she has made oversight of the Department of Education's student loan program a top priority since entering Congress, unveiled a new tool Wednesday that seeks to keep tabs on the agency's secretary, Betsy DeVos.

The Massachusetts Democrat and outspoken critic of the new education head announced via video that she was launching the "DeVos Watch" project in an attempt to hold the agency accountable to the public.

Stressing that the effort should not be partisan, Warren urged voters to join her in ensuring that students are put "ahead of profits" at the Education Department.

The senator, who explained that DeVos Watch will seek answers on behalf of the public, said she would check in with voters "as things develop so we can all stay vigilant."

"We'll raise questions and concerns and when we get reasonable answers everybody will benefit from hearing them. And, when we don't? Everybody's going to see that too," she said in the video. "Because accountability is about making government work for everyone."

The senator's video announcement came in addition to a Wednesday CNN op-ed in which she raised concerns about proposed changes to the student aid program included in President Donald Trump's budget plan, questioned DeVos' leadership and made the case for agency oversight.

Warren, who further discussed her new initiative in the op-ed, added that DeVos Watch will specifically seek information about ED actions surrounding federal student loans and grants through Freedom of Information Act requests, public interest litigation and Inspector General investigations.

The public, she added, will also be able to directly track the agency's actions, file whistleblower tips and submit oversight suggestions.

"Regardless of political party, I'm hopeful that other policymakers will join me in efforts to hold the Department of Education accountable for serving our students -- not the industries that make money off them," she wrote in the op-ed. "We all have an interest in a well-run, fiscally responsible, corruption-free student aid program that puts students first. That is Secretary DeVos' job -- and it is Congress' job to make sure she does it."

Warren was among several Massachusetts Democrats to speak out against the Senate's historic February vote to confirm DeVos to the post of education secretary.

The senator argued that it is hard to imagine a "less qualified or more dangerous person" for the job and accused Republicans of "ram(ming) this nomination down the throats of the American people sideways."

Senators voted 51 to 50 to add DeVos to Trump's cabinet, with Vice President Mike Pence using his tie-breaking authority to approve the president's nominee.
