"I don't take money from big banks,"  Bernie Sanders said during the NBC News' Democratic presidential candidates debate Sunday. "I don't get personal speaking fees from Goldman Sachs."

Sanders was talking about... you guessed it. Hillary Clinton. In this election so far, Clinton has received hundreds of thousands of dollars from employees of the big banks.

From 2013-2015 she made almost $3 million in speaking fees for events tied to financial institutions, including Goldman Sachs, Morgan Stanley and Bank of America.

Clinton is also seen as fairly easy on big banks. She wants to build on the Dodd–Frank Wall Street Reform and Consumer Protection Act, which Obama signed into law during the great recession to prevent banks from taking huge risks. Sanders, on the other hand, wants to reinstate Glass-Steagall Act, which separated commercial banking from riskier investment banking.

"Can you really reform Wall Street when they are spending millions and millions of dollars on campaign contributions and when they are providing speaking fees to individuals?" Sanders asked.

Clinton has said she would break up big banks if need be and that her plan expands on Dodd-Frank regulations.

"It goes much further because both the Gov. (Martin O'Malley, of Maryland) and the Sen. (Sanders) have focused only on the big banks," Clinton said. "Lehman Brothers, AIG, the shadow banking sector were as big a problem in what caused the great recession. I go after them."
