Facebook founder and CEO Mark Zuckerberg had trouble Wednesday reassuring Rep. Jan Schakowsky that the data breach of user information was limited to Cambridge Analytica.

“You said yesterday that [Aleksandr] Kogan also sold data to other firms. You named Eunoia Technologies. How many are there total and what are their names? Can we get that?” the Illinois Democrat asked Zuckerberg during a House Energy and Commerce Committee hearing.
