Google's top government affairs official said on Monday that the search engine does not discriminate against conservative viewpoints and that he will reiterate that to a U.S. Senate panel on Tuesday.

Karan Bhatia, vice president of global government affairs and public policy at Alphabet Inc.'s Google and a former official under Republican President George W. Bush, said in an op-ed published on Monday on Fox News's website that he will tell senators that "Google's products are not politically biased."

He added that the company goes "to extraordinary lengths to build our products and enforce our policies in such a way that political leanings are not taken into account."
