Facebook’s Zuckerberg throws punches about privacy during Congressional tour

When Mr. Zuckerberg went to Washington, his boyish grin and soft-spoken attitude were put on hold. He let Congress have it and was not afraid to tell the press all about it.

Facebook CEO Mark Zuckerberg is visiting Capitol Hill to lobby members of Congress in support of comprehensive immigration overhaul legislation.

Zuckerberg was pressing his case in private meetings Wednesday and Thursday at the Capitol, including with Republican and Democratic members of House and Senate leadership.
