Trump's remarks came hours after he singled out Google for criticism on his Twitter account, accusing the tech giant of limiting access to conservative media sources in favor of what he described as the "Fake News Media". Fake CNN is prominent.
Trump's claim of bias by Google was the result of, ironically, a biased study by PJ Media, a conservative outlet.
As Media Matters for America watchdog Matthew Gertz quickly pointed out, the president's accusations - including a suspicious statistic that "96% of results on "Trump News" are from National Left-Wing Media", - were seemingly pulled from Monday night's episode of Lou Dobbs Tonight on Fox News.
Trump's attack against the Alphabet Inc unit follows a string of grievances against technology companies, including social media Twitter Inc and Facebook Inc, which he has accused of silencing conservative voices, and Amazon.com Inc, which he has said is hurting small businesses and benefiting from a favorable deal with the U.S. Postal Services.
He said: "They are controlling what we can and cannot see".
Trump added: "Google and Twitter and Facebook - they are really treading on very, very troubled territory and they have to be careful". In response, the search engine said its searches aren't politically biased.
There are several factors that contribute to those results, including "freshness" of content and the extent to which it contains original reporting, as opposed to just aggregation or commentary on the news.More news: British Prime Minister, Theresa May
Allegations of social media bias and censorship have made their way to Congress, where lawmakers have held two hearings this year on the so-called practice of "social media filtering".
The claims appeared to be based on a report from the Trump-friendly news site PJ Media which relied on an analysis chart by conservative news host Sharyl Attkisson that categorized major news outlets such as the New York Times, CBS and CNN as "left wing".
Google's search results are tailored to the individual who is searching, such as their location.
It may be tempting to dismiss these pre-dawn tweets as nothing more than the restless ramblings of a tech-illiterate old man. (Trump uses Twitter on smartphones, but not email, and has little experience with desktop computers.) They also serve as a form of guidance from the president of the United States.
Trump in July lashed out at the European Union in response to a record $5 billion fine against Google over its mobile phone operating system, calling Google one of America's "great companies". Twitter denied the claim. And of course, the results have a lot to do with the specific terms you choose to search.
Mountain View, California-based Google had no immediate comment.
"We'll let you know", Kudlow said.
Trump recently began complaining about the issue as social media companies moved to ban right-wing "Infowars" conspiracy theorist Alex Jones from their platforms.
