President Trump on Monday, Aug. 19, accused the search giant of manipulating millions of voters in favor of former Secretary of State Hillary Clinton in the 2016 election, suggesting the company “should be sued.”

“Wow, Report Just Out! Google manipulated from 2.6 million to 16 million votes for Hillary Clinton in 2016 Election! This was put out by a Clinton supporter, not a Trump Supporter! Google should be sued. My victory was even bigger than thought!” the president tweeted. 

President Trump seems to be referring to a Dr. Robert Epstein study that claimed that Google generated a minimum of 2.6 million votes for Hilary Clinton through deceptive manipulation of search results.

In June, Epstein, a psychologist who works for the American Institute for Behavioral Research and Technology testified before the Senate Judiciary Committee, “Biased search results generated by Google’s search algorithm likely impacted undecided voters in a way that gave at least 2.6 million votes to Hillary Clinton (whom I supported).”

Google representative in a statement on Monday said, “This researcher’s inaccurate claim has been debunked since it was made in 2016.” the representative said. “As we stated then, we have never re-ranked or altered search results to manipulate political sentiment. Our goal is to always provide people with access to high quality, relevant information for their queries, without regard to political viewpoint.” 

The president’s comments also might refer to documents leaked by a Google insider to Project Veritas, a right-leaning investigative journalism nonprofit. Zachary Vorhies who worked as a software engineer at Google for eight years, and had been saving hundreds of documents over one year, decided go public to show how bias the search results that Google displays. Vorhies said, “I saw something dark and nefarious going on with the company and I realized that they were going to not only tamper with the elections, but use that tampering with the elections to essentially overthrow the United States.”

This is not the first time President Trump has criticized the tech giant for discriminating against conservatives, “Social Media is totally discriminating against Republican/Conservative voices,” the president said in tweet a day earlier. 

According to Politico, in early August the White House was considering an executive order that would address anti-conservative bias coverage from social media and internet companies.

President Trump also warned that he would be “watching Google very closely,” after another former Google employee revealed that he believed Google will try to prevent President Trump to get re-elected in 2020. The former employee also claimed he had been fired for his political viewpoint.
