Ted Cruz Rails Against Zuckerberg Over Political Bias, Invokes Diamond & Silk's Facebook Page

Issuing his mea culpa before Congress Tuesday, Facebook CEO Mark Zuckerberg was grilled by Sen. Ted Cruz (R-TX) who accused the company of partisanship and failing to serve as a "neutral public forum."

Asked to explain whether the site was truly neutral, Zuckerberg noted that it bans hate speech, nudity and terrorist content. However, Cruz insisted it was biased.

"There are a great many Americans who I think are deeply concerned that Facebook and other tech companies are engaged in a pervasive pattern of bias and political censorship," he said. "There have been numerous instances with Facebook."
