Democratic Senator Elizabeth Warren of Massachusetts has earned a reputation for holding corporations and the executives who profit from them accountable.

Such was the case during a Senate Banking, Housing, and Urban Affairs Committee hearing on the Federal Reserve and the U.S. Economy this past Wednesday, which featured testimony from CEOs of major banks.

Among those CEOs was JPMorgan Chase executive Jamie Dimon—with whom Warren has come to barbs before.

This time, Warren pressed Dimon over the bank's $1.5 billion in revenue driven by overdraft fee charges during the pandemic. JPMorgan enforced these overdraft fees despite regulators urging banks to automatically waive overdraft fees during the pandemic and despite the Federal Reserve waiving overdraft fees for banks in their own Fed accounts.

What followed was a tense exchange.

Labeling Dimon the "star of the overdraft show," Warren said:

"Your bank, JPMorgan, collects more than seven times as much money in overdraft fees per account than your competitors. So, Mr. Dimon, how much did JPMorgan collect in overdraft fees from their consumers in 2020?"

Dimon claimed Warren's numbers were "totally inaccurate."

As Dimon talked over her, Warren said:

"Sir, these are public numbers. Can you just answer my question? How much did JPMorgan collect?"

Dimon said that he didn't have the number in front of him, but that JPMorgan waived some overdraft fees upon request.

Warren responded:

"I actually have the number in front of me. It's $1.463 billion. That's nearly one and a half billion dollars that you collected from your customers. Now, do you know how much JPMorgan's profit would've been in 2020 if you had followed the recommendation of the regulators and waived overdraft fees to help struggling consumers? In other words, without that overdraft money, would your bank have been in financial struggle?"

Dimon once again deflected before Warren gave him the answer: $27.6 billion.

The Senator concluded:

"You and your colleagues come in today to talk about how you stepped up and took care of customers during the pandemic, and it's a bunch of baloney."

People were thrilled at the takedown.

But while countless people enjoyed seeing Dimon's feet held to the fire, they still want to see action and expanded regulation imposed on big banks.

That's unlikely to happen as long as the filibuster remains unchanged.
