President Trump has attacked Google in a series of tweets referencing allegations of the company's bias and anti-conservative culture.
The president claimed Google chief executive Sundar Pichai had been in the Oval Office "working very hard to explain how much he liked me" and disputing criticisms by rivals and right-wing commentators.
Mr Trump said: "It all sounded good until I watched Kevin Cernekee, a Google engineer, say terrible things about what they did in 2016 and that they want to 'Make sure that Trump loses in 2020'."
Mr Cernekee appeared on Fox & Friends the evening before the tweets, claiming that Google executives cried on stage when President Trump won the election in 2016 and "vowed that it would never happen again".
Google has not responded to Mr Cernekee's claims.
The president also criticised Google on Twitter last August, saying it "rigged" search results to give greater prominence to negative stories about him.
Those claims came the morning after they were broadcast on the Lou Dobbs Tonight programme, a show on Fox Business Network.

He also said that journalist Peter Schweizer had "stated with certainty that they suppressed negative stories on Hillary Clinton, and boosted negative stories on Donald Trump".
Mr Trump added: "All very illegal. We are watching Google very closely!"

Among the matters Google's chief executive is said to have discussed with the president is the claim it was working with the Chinese military.
That claim appears to have originated from Peter Thiel, a Silicon Valley billionaire and prominent supporter of Mr Trump.
Mr Thiel suggested Google's alleged attempt to work with the Chinese military was "seemingly treasonous", and questioned – without providing evidence – whether Google had been "infiltrated" by foreign intelligence agencies.
Last year's claims on the Lou Dobbs show said 96% of Google results were biased against the president and cited what Mr Trump described as the "National Left-WinRead More – Source[contf] [contfnew]
