After hours of questioning Mark Zuckerberg in Washington, DC, in April, two US senators aren't done with the Facebook CEO. 

Sens. John Thune, a Republican from South Dakota, and Bill Nelson, a Democrat from Florida, sent more questions to Facebook on Tuesday, in the wake of more concerns over data from the world's largest social network. Thune, the chairman of the Senate Committee on Commerce, Science and Transportation, and Nelson, a ranking member on the committee, want to know if Zuckerberg lied during his initial appearance in April.
