Sen. Elizabeth Warren (D-Mass.) made clear Wednesday she has no interest in seeing a Clinton administration filled with officials tied to Wall Street.

Speaking at an event hosted by the Center for American Progress Action Fund in Washington, Warren detailed her support for Hillary Clinton for president. But she also made clear that if Clinton gets elected, Warren will be interested in who fills top spots in the administration.

{mosads}Echoing the liberal mantra of “personnel is policy,” Warren singled out financial firms as the home of power players who would love to move the levers of power in Washington before moving on to another lucrative gig in the private sector. And she made clear that trying to confirm those types of officials would be an uphill battle against the likes of her and other liberals.

“When we talk about personnel, we don’t mean advisers who just pay lip service to Hillary’s bold agenda, coupled with a sigh, a knowing glance, and a twiddling of thumbs until it’s time for the next swing through the revolving door,” she said. “We don’t mean Citigroup or Morgan Stanley or Blackrock getting to choose who runs the economy in this country so they can capture our government.”

Liberals like Warren have publicly thrown their support behind Clinton despite grumbling from many on the left about the deregulatory push that closed out the final years of President Bill Clinton’s time in office. But accompanied by that support is an underlying vow to fiercely police top government officials if Hillary Clinton wins.

As a candidate, Clinton has made several nods to progressives in building out her policies, including vowing to punish bank executives and break up big banks if necessary, and opposing the Trans-Pacific Partnership.

Warren on Wednesday hailed Clinton’s agenda and vowed to work “my heart out to elect Hillary Clinton.”

“Hillary Clinton has put together a strong, progressive agenda, chock-full of policy proposals that will help level the playing field and grow opportunities for working families,” she said.

And as she has in the past, Warren carved out ample time to go after Republican nominee Donald Trump, calling him a “thin-skinned, racist bully” with no clear agenda to help working families.
