Mediaite noted how during a recent media appearance, Massachusetts Democratic Sen. Elizabeth Warren gave her whole-hearted endorsement for another presidential run by Joe Biden.

Yet in a bombshell moment, Warren didn't express the same confidence in Vice President Kamala Harris. 

"Tremendous amount done"

Warren's comments were made on Friday during an interview with Boston Public Radio, and came in response to a question about Biden's plans for 2024.

Up First:
We had to switch over to our studio in Brighton. But we still have @SenWarren with us to discuss the debate around the debt ceiling, cryptocurrency regulation and the Senate's focus on Ticketmaster.

"Should Joe Biden run again for president?" the interviewer asked, noting, "He’ll be 86 by the time his second term is over."

Warren was unequivocal in her reply, saying, " Yes, he should run again. And he is running again because he has gotten a tremendous amount done."

"It’s been two years. He’s had this hideous possible majority in the United States Senate and only a very small majority in the House. And yet look at what we’ve done," the left-wing senator gushed.

Warren then brought up the Inflation Reduction Act and the Creating Helpful Incentives to Produce Semiconductors and Science Act of 2022 (CHIPS Act) as being proof of the president's political prowess.

Senator hesitant about endorsing Harris

However, Warren was far more reserved in her remarks when the host pointed out that Biden's advanced age makes the vice president "even more important."

Upon being asked if Kamala Harris should remain on her party's ticket, Warren deflected, replying, "Y'know, ah, you know, I really want to defer to what makes Biden comfortable on his team."

Poll shows Harris losing to Trump and DeSantis

"I’ve known Kamala for a long time," the senator went on. "I like Kamala. I knew her back when she was attorney general."

"And I was still teaching. And we worked on the housing crisis together. So we go way back," Warren added. "But they need, they have to be a team. And my sense is they are. I don’t mean that by suggesting I think there are any problems. I think they are."

Warren's hesitancy over endorsing Harris could be due to polling data which suggests that she would be a weak candidate when put up against either former President Donald Trump or Florida Republican Gov. Ron DeSantis.

A survey conducted by Harvard Harris between January 18 and January 19 showed Trump beating the vice president in hypothetical race by six points while DeSantis bests her by five in a hypothetical contest.
