Democratic presidential candidate and Vermont Sen. Bernie Sanders (I) offered a first glimpse on Sunday of some of the people he might consider for his cabinet in a potential Sanders administration, and a few that he certainly won’t.

“My cabinet would not be dominated by representatives of Wall Street,” Sanders said on CNN’s “State of the Union.” “I think Wall Street’s played a horrendous role in recent years, in negatively impacting our economy and in making the rich richer. There are a lot of great public servants out there, great economists who for years have been standing up for the middle class and the working families of this country.”

Prompted by host Jake Tapper, Sanders went on to praise Paul Krugman, the New York Times columnist and Nobel Prize-winning economist. Krugman is a vocal opponent of tax cuts for the rich, and he has warned readers for years about the dangers of income inequality. “Krugman does a great job,” Sanders said.

Also doing a great job, Sanders said, is Columbia University economics professor and Nobel laureate Joseph Stiglitz, whose recent work has focused on the perils of radical free markets, such as those espoused by some in the libertarian wing of the GOP.

Sanders also singled out Robert Reich, the former labor secretary under President Bill Clinton, now a professor at the University of California at Berkeley: “I think [he] is doing a fantastic job.” Reich has long been an influential backer of labor unions, which have come under attack from Republican governors in recent years.

Still, Sanders said, “it’s a little bit too early, I must say, to be appointing a cabinet. Let me get elected first.”
