It didn’t take long for Sen. Bernie Sanders to seize on critical comments from the head of Goldman Sachs.

In an interview with CNBC on Wednesday, Goldman Sachs GS, -2.91% Chairman and CEO Lloyd Blankfein said the Sanders candidacy “has the potential to be a dangerous moment.”

“Not just for Wall Street, not just for the people who are particularly targeted, but for anybody who is a little bit out of line,” Blankfein said. Read full CNBC transcript with Blankfein.

For the Vermont senator seeking the Democratic nomination for the presidency, the comments were music to his ears.

Sanders said it was “beyond comprehension” that Blankfein would lecture him after the huge bailouts Wall Street received for “their greed and recklessness.”

Wall Street continues to be a major point of contention between Sanders and former Secretary of State Hillary Clinton. Sanders wants to revive the Glass-Steagall Act that separated commercial and investment banks, a law Clinton’s husband, President Bill Clinton, repealed.

Clinton says she wants to focus more on restricting so-called shadow banks. Sanders favors a tax on high-frequency trading to pay for college tuition; Clinton favors a more narrow tax focused on transactions with high levels of cancellations.

Sanders and Clinton are scheduled to debate Thursday night. Polls suggests Sanders will win next week’s primary in New Hampshire, but Clinton will secure the Democratic nomination.
