A top Biden adviser has torn into hypocritical lefties who are supporting billionaire Tom Steyer for California governor.

Neera Tanden, a former senior adviser to President Joe Biden, reacted to recent endorsements of the hedge fund titan turned climate activist, calling them “so funny.”

“I really like Tom Steyer – I have known him a long time. But I have to say I find it so funny that DSA is endorsing a billionaire who started his career at Goldman Sachs,” Tanden wrote on X.

The comment came days after the Democratic Socialists of America issued an endorsement of Steyer, who is running for California governor as a Democrat.

The nation’s largest socialist organization backed the billionaire investor, who made a fortune in private equity before spending hundreds of millions of dollars on political campaigns — first in his 2020 presidential run and now in his bid for California’s governorship.

In its voter guide, the group acknowledged the tension in supporting him, writing: “Even if he glibly considers himself a ‘class traitor,’ his wealth was earned through the exploitation of the working class.”

It continued: “Much of his wealth was also invested in private prisons and coal mining, accumulated by the same things he now decries.”

The guide also noted internal skepticism while still offering conditional support, adding: “However, the most progressive of the current viable candidates for governor is Tom Steyer. Time will tell whether he’s truly a class traitor.”

Steyer is not a member of the DSA.

He built his multibillion-dollar fortune primarily through Farallon Capital Management, a San Francisco-based hedge fund he founded in 1986.

Specializing in risk arbitrage and distressed assets, he grew the firm into a major investment operation managing more than $20 billion before stepping away in 2012 to focus on climate advocacy and politics.
