Progressive icon Elizabeth Warren still isn’t ready to endorse a candidate for the Democratic presidential nomination. But she says she’s cheering on Bernie Sanders.

The Massachusetts Democrat’s comment came Thursday in response to a question about whether Sanders, a democratic socialist, should drop out of the race against front-runner Hillary Clinton.

‘‘He’s out there. He fights from the heart. This is who Bernie is,’’ Warren said, according to a video of the news conference. ‘‘He has put the right issues on the table both for the Democratic Party and for the country in general so I’m still cheering Bernie on.’’

Warren wouldn’t say who got her vote in the Massachusetts primary. She said she will endorse a candidate but she doesn’t have a timeline.

“I think it is right what’s happening in the Democratic primary,” she said. “We’re hearing from two candidates who are out there talking about the issues that affect hardworking people across the country."

The admiration is apparently mutual between Warren and Sanders. Sanders was asked Wednesday on the progressive Web show “The Young Turks” whether Clinton is liberal enough to be in his Cabinet if he were to win.

“There are other people that I would probably go to before Hillary Clinton, people like Elizabeth Warren for example,” he said.

Sen. Elizabeth Warren still hasn't endorsed, but how much does it matter?
