The titans of Wall Street got hauled onto Capitol Hill on Wednesday to get grilled about whether their “too big to fail” banks could crash the economy.

The chief executives of seven top US financial giants — including JPMorgan Chase’s Jamie Dimon and Goldman Sachs’ David Solomon — faced questions from lawmakers about systemic risks to the US banking system — the first such hearing in nearly a decade.

“I’m concerned that several of these [banks] are simply too big to manage,” said US Rep. Maxine Waters (D-Calif.), the chair of the House Financial Services Committee.

For nearly seven hours, committee members pelted the CEOs with questions about everything from Russian money laundering to overdraft charges.

Nevertheless, they failed to dig into some of the industry’ s biggest scandals of late. Not a single lawmaker, for example, bothered to ask Solomon about the bank’s involvement with a $6 billion Malaysian bribery scheme — despite Solomon’s reported approval of the deals and forecasts of hefty settlements weighing on the bank’s stock price.

Early reports had said that the bankers would let Dimon field most of the questions — but Rep. Waters tried to put a stop to that before the questioning began.

“We know that he’s very smart, we know he’s been around for a long time,” Waters said of Dimon. “But it’s not just his show today.”

In his opening statement, Dimon said that the risks that led to the global financial crisis in 2008, like the bankruptcy of Lehman Brothers, aren’t a big concern today, although he did point to large, unregulated non-bank mortgage lenders as a risk.

“Lehman simply would not happen again,” he said.

Near the end of the hearing, Rep. Alexandria Ocasio-Cortez (D-NY) grilled Dimon on whether more bank executives should have gone to prison for their role in the 2008 financial crisis.

“I think if people broke the law they should go to jail,” Dimon said.

The executives agreed that cybersecurity was the biggest threat to the financial system, and they were meeting with Treasury Secretary Steven Mnuchin and members of the Department of Homeland Security following the hearing.

Other banks represented were Citigroup, Morgan Stanley, State Street, Bank of America, and Bank of New York.

The hearing was in stark contrast to the last time a group of Wall Street CEOs had been lambasted by Congress in 2009, after receiving some $176 billion in bailout money.
