Tuesday on Fox News Channel's "Tucker Carlson Tonight," psychologist Dr. Robert Epstein explained how a recently released Project Veritas undercover video, which shows Google executive Jen Gennai proclaiming the tech giant she works for is determined to prevent the re-election of Donald Trump, verified what he has concluded from his research.

Epstein, a senior research psychologist at the American Institute for Behavioral Research and Technology, told Fox News' Tucker Carlson it confirmed that Google could influence votes and is willing to do so.

"I'm not surprised in the least," Epstein said. "It confirms in glowing terms, or in very ugly terms if you want to look at it that way, that Google not only has the power to shift opinions and votes on a massive scale but they exercise this power. This is what I measure in my research. So, I can tell you fairly precisely how many votes they can shift. I can tell you fairly precisely how many votes they shifted in 2018."
