The answer the lawyers came back with was yes: There is nothing in the Constitution that bars the vice president from also serving as treasury secretary. Sanders has made no final decisions on a potential running mate or cabinet officers, considering such questions premature and presumptuous, but the research into the question of Warren’s dual eligibility reflects the political affinity that has long existed between the two — an affinity that was dealt a setback over the past week, as the pair clashed over the contents of a year-old private conversation. The sources were not authorized to speak publicly about internal deliberations…

Not long after meeting with Sanders at the end of 2018 to discuss her impending presidential run, Warren hosted an off-the-record dinner with a number of journalists, according to sources with knowledge of it. At the dinner, Warren was asked about her meeting with Sanders, and in the course of the discussion, she relayed that Sanders had warned that he didn’t believe a woman could beat Trump in 2020. Different reporters recalled the comments differently, a mirror image of the dispute between Warren and Sanders over exactly what Sanders said — with Warren saying that Sanders argued a woman couldn’t beat Trump, while Sanders said that he only said Trump would weaponize misogyny against a woman, not that it would work. (The Intercept was not at the dinner. Most politicians hold informal, off-record dinners or meetings with journalists, though it’s not something Sanders is known to do. Occasionally details from those meetings leak, but it’s rare.)
