Accusations that Silicon Valley heavy hitters are suppressing conservative voices online have been part of an ongoing narrative this year, pushed by Republican lawmakers and President Donald Trump, who's tweeted about it. Facebook and Twitter executives were questioned about their companies' practices during congressional testimony earlier this year. Google has long denied the accusations, a stance Pichai reiterated many times during the three-and-a-half-hour hearing.  

"I lead this company without political bias and work to ensure that our products continue to operate that way," Pichai said in his prepared remarks. "To do otherwise would go against our core principles and our business interests. We are a company that provides platforms for diverse perspectives and opinions -- and we have no shortage of them among our own employees."
