Since leaving government two years ago, President-elect Joe Biden’s pick for treasury secretary has earned more than $7.2 million in speaking fees from Wall Street and major corporations, including Citigroup, Goldman Sachs, and Google, according to financial disclosure forms.

In a 21-page disclosure form, former Federal Reserve Chairwoman Janet Yellen details more than 60 sources of income, including her benefits from the University of California, Berkeley, where she is a professor emeritus. Her speaking fees make up the bulk of her income, however.
