U.S. President Donald Trump on Tuesday accused Google's search engine of promoting negative news articles and hiding "fair media" coverage of him, vowing to address the situation without providing evidence or giving details of action he might take.
It comes after Mr Trump has previously attacked Google, Twitter and Facebook for being "very dishonest media".
He claims that "literally thousands and thousands of complaints" have been received, adding, "It's not fair to large portions of the population".
"Every year, we issue hundreds of improvements to our algorithms to ensure they surface high-quality content in response to users" queries.
Larry Kudlow, the president's top economic adviser, told reporters later that the White House is "taking a look" at whether Google searches should be subject to some government regulation.
Adds Google: "We never rank search results to manipulate political sentiment". In other words, they have it RIGGED, for me & others, so that nearly all stories & news is BAD. There's an irony with Trump using Twitter to accuse Google of bias.
The president, who has said he runs on little sleep, jumped onto Twitter before dawn Tuesday to rehash his recent complaints about alleged suppression of conservative voices and positive news about him.More news: Chaos as Gatwick airport uses whiteboards after digital departure screens fail

The president also went on to suggest that he had somehow analysed the results on a search for the term "Trump News" and found that nearly all of the stories that came upwere "left-wing".
"This is a very serious situation-will be addressed!"
While the exact science behind Google searches on the internet is kept secret, its basic principles are widely known to be generated with a variety of factors measured by the company's algorithms.
In March, Google announced it would spend more than $A408 million over the next three years to improve its search results following the rise of "fake news".
Mountain View, California-based Google had no immediate comment.
Highly trafficked and cited websites like CNN.com and NYTimes.com, two of the most Trump's most frequent targets, often appear first in search results.
Some Republican US lawmakers have also raised concerns about social media companies removing content from some conservatives, and have called Twitter's chief executive to testify before a House of Representatives panel on September 5. While some company executives may lean liberal, they have long asserted that their products are without political bias. Jones was also temporarily suspended on Twitter.
