Hillary Clinton threw some major shade at President Trump on Monday night after he tried bashing her on Twitter earlier in the day.

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

Replying a few hours later, Clinton said: “The debunked study you’re referring to was based on 21 undecided voters. For context that’s about half the number of people associated with your campaign who have been indicted.”

The former first lady and secretary of state appeared to be delivering a veiled shot at Trump and his campaign supporters who got busted as a result of the Mueller probe.

The president’s tweet was referring to a study by psychologist Robert Epstein, which was reported Monday by Fox Business. Epstein, himself, criticized Trump’s claim in an interview with CNN.

“I don’t have any evidence that Google manipulated anything,” Epstein said, noting how the pro-Clinton bias was “sufficient to have shifted between 2.6 and 10.4 million votes” to her, not 16 million.

“I just have evidence that there was this bias — highly statistically significantly bias,” he explained.

However, Google insists that Epstein is incorrect.

“This researcher’s inaccurate claim has been debunked since it was made in 2016,” the company told CNN. “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.”
