US senators Amy Klobuchar, a Democrat, and John Kennedy, a Republican, have also called for
a hearing about data security and said they want to question Facebook chief executive Mark Zuckerberg, and the heads of other tech companies.
While the
hearings were ostensibly primarily
about data security and privacy, Zuckerberg's own words indicate he was not necessarily limiting them to the privacy issue, and lawmakers» questions covered everything from content censorship to Facebook's responsibility for illegal pharmaceutical ads.
