(CNN) – Sen. Elizabeth Warren said Sunday that Hillary Clinton is "terrific" and she hopes the former secretary of state will run for president in 2016.
"You know, all of the women - Democratic women, I should say, of the Senate urged Hillary Clinton to run. And I hope she does," the freshman Democrat from Massachusetts said on ABC.
But Warren didn't give a firm answer when asked by host George Stephanopoulos if she'd endorse Clinton, the overwhelming favorite for the Democratic nomination, should she launch a campaign.
A tough critic of Wall Street and big banks, Warren's staple as a politician has been advocating for consumers against unfair practices in the banking industry. And though she's adamantly denied plans to run for the White House, she has a large cadre of support among progressives urging her to launch a campaign.
She's been making the TV show circuit coinciding with the release of her new book, "A Fighting Chance," which talks about her role in the creation of the Consumer Financial Protection Bureau. She was a senior adviser under President Barack Obama in setting up the agency before returning to Massachusetts to run for the Senate.
In the past, Warren has criticized Clinton for her ties to the Wall Street world, more specifically for accepting $140,000 in campaign contributions from the banking industry when serving as a senator from New York.
Asked Sunday if she feared Clinton would capitulate to big banks as commander in chief, Warren dodged the question, instead focusing on her own fight for the cause.
"I've made it clear all the way through this book - and really what I've been working on for the last 25 years - that I'm worried a lot about power in the financial services industry," she said. "It's a central issue for me. It's something I'm going to keep talking about. And I'm going to keep talking about it with everyone."
Pressed further on whether she thinks Clinton will fight for Wall Street reforms, Warren again pivoted back to her commitment to the agency and its work.
"I'm going to keep talking about this issue. And I'm going to keep pushing on this issue," she said.
Warren wrote in her previous book, "The Two Income Trap," released in 2003, about Clinton’s support for a bankruptcy bill Warren opposed: "As First Lady, Mrs. Clinton had been persuaded that the bill was bad for families, and she was willing to fight for her beliefs.
“As New York’s newest senator, however, it seems that Hillary Clinton could not afford such a principled position. ... The bill was essentially the same, but Hillary Rodham Clinton was not.”
Warren's latest book softens the tone of that criticism. And despite her reservations Sunday, Warren has been largely supportive of a potential Clinton candidacy. She and a number of senators signed a letter urging the former secretary of state to run.
