Sen. Elizabeth Warren again unloaded on President-elect Donald Trump's pick of Steven Mnuchin to head the Department of Treasury Wednesday night, calling it a "180-degree" turn from his campaign promise to fight back against Wall Street.

"Donald Trump promised that he was not going to have a government that was going to work for Wall Street. He promised that he was not going to have a revolving door," Warren told CNN's Anderson Cooper. "And then he turns around in his first big economic appointment is to appoint a Wall Street insider. A guy who made millions of dollars off mortgages that crushed families financially."


Warren's words echoed her Tuesday statement blasting the 17-year Goldman Sachs veteran as "the Forrest Gump of the financial crisis." The Trump campaign's Wednesday announcement of the Mnuchin pick has sparked strong opposition from progressive groups and politicians, including fellow liberal Sen. Sherrod Brown.

Pressed by Cooper on whether she'd be willing to find common ground with Trump and his appointments, citing pessimism about political gridlock among Americans, Warren said her priorities lay in protecting those of lower socioeconomic standing.

"I think what a lot of Americans are sick of is a government that works for those at the top," she said. "I think the Donald Trump tapped into that anger and now Donald Trump is doing 180 degrees on it and putting Wall Street insiders into exactly the jobs where he criticized Wall Street insiders before."

Trump hailed Mnuchin on Wednesday as "a world-class financier, banker and businessman" who played a key role in developing the president-elect's economic plan.

The 53-year-old hedge fund CEO has expressed skepticism of the Dodd-Frank Act, a piece of legislation intended to regulate how Wall Street operates championed by Warren.

Warren also repeated criticisms of Trump's addition of Breitbart News' Steve Bannon to his transition team Wednesday, saying the move, along with the Mnuchin pick, showed Trump isn't looking out for a large portion of Americans.

"If he wants to run his administration on bigotry and on Wall Street insiders, trickle-down economics that helps a handful of people at the top and leaves everybody else behind, I can't be part of that," she said.
