Texas Sen. Ted Cruz says many Americans are concerned that Facebook is biased against conservatives.
Questioning Facebook CEO Mark Zuckerberg at a Senate hearing Tuesday, the Republican senator and former GOP presidential candidate said that to many people there "appears to be a pervasive pattern of political bias" after some conservative pages were taken down from the platform. In a series of pointed questions, Cruz asked Zuckerberg if he had tracked the political affiliations of his employees.

Zuckerberg said he had not. But he noted that the company is based in left-leaning Silicon Valley, and said "it is a fair concern."
Cambridge Analytica, the data-mining firm alleged to have collected private Facebook data on users, has boasted of helping Cruz win the Iowa caucus in 2016.
