Senator Frank Pallone of New Jersey posed three questions to Zuckerberg asking him to answer with only a yes or a no.
When asked if Facebook would commit to changing its default settings “to minimise, to the greatest extent possible, the collection of user data”, Zuckerberg resorted to an extended pause.
“This is a complex issue that deserves more than a one word answer,” he said.
“That's disappointing,” replied the senator.
Pallone later gave Zuckerberg the option of discussing the possibility of minimising user data collection separately to which the Facebook chief agreed.
