JPMorgan Chase said on Tuesday that it's identified the misuse of COVID-19 relief funds by customers, and is investigating whether some of the bank's employees also may be have been involved.
In a memo to staff signed by a dozen senior leaders, including CEO Jamie Dimon, the investment bank said such conduct "does not live up to our business and ethical principles -- and may even be illegal."
The potentially illegal conduct "includes instances of customers misusing Paycheck Protection Program loans, unemployment benefits and other government programs," according to a memo obtained by ABC News.

JPMorgan Chase declined ABC News' request for comment on Tuesday.
