Is Google Search Rigged Against President Trump?

In a series of tweets Tuesday, President Trump claimed that Google's search algorithm is "rigged" against him to only show negative and, as he describes it, "fake news."

"They're really treading on very very troubled territory and they have to be careful. It's not fair to large portions of the population," the president said.

Trump's top economic adviser, Larry Kudlow, told reporters that the White House will be looking into the issue.

“Search is not used to set a political agenda and we don’t bias our results toward any political ideology," Google responded in a statement Tuesday. "We never rank search results to manipulate political sentiment.”

But, how much do we really know about how Google Search works?
