Sen. Elizabeth Warren, D-Mass., sparked a flurry of speculation on social media over the weekend after she stopped short of backing Vice President Harris as President Biden’s 2024 running mate.

During an interview on Boston Public Radio, Warren was asked if Harris should be Biden’s running mate. 

“I really want to defer to what makes Biden comfortable on his team,” she responded. “I’ve known Kamala for a long time. I like Kamala. I knew her back when she was an attorney general, and I was still teaching and we worked on the housing crisis together, so we go way back.”

“But they need — they have to be a team,” she added, “and my sense is they are — I don’t mean that by suggesting I think there are any problems. I think they are.”

Warren said during an interview with Politico that she was “very happy” about Biden’s re-election and said he would likely not face a primary challenge.  

“The circumstances are that Joe Biden is running,” Warren said. “I’m very happy about that. I am not running for president, I’m running for Senate.”
