According to The Hill, Obama has advised reluctant donors to back the Massachusetts Democrat despite her plans to separate them from as much of their wealth as she can. If she becomes the nominee, according to Obama, donors will have no choice but to throw their support behind her.

The former president has stopped short of an endorsement of Warren in these conversations and has emphasized that he is not endorsing in the Democratic race. 

But he also has vouched for her credentials, making it clear in these private sessions that he deems her a capable candidate and potential president, sources say. -The Hill

"He's asked all of the candidates who have sought his advice three questions: Is your family behind you? Why you? And why now? She checked the box for all," one longtime Obama ally told The Hill, adding "I think he feels licensed to give an opinion on her because he's 'hired' her."

Of course, Obama also hired 2020 candidate Julián Castro to be secretary of Housing and Urban Development, and then there's Joe Biden - Obama's former VP which he's been awkwardly silent on this whole time. According to The Hill, Obama remains "incredibly fond" of Biden and is watching his campaign with interest.
