When Facebook CEO Mark Zuckerberg testifies before Congress this week, he'll address House and Senate members who've received sizable campaign contributions from Facebook employees and its political action committee.

Commerce Committee members received $369,000 in contributions, while Judiciary Committee members received $235,000 over the period.
