WASHINGTON: President Donald Trump has voiced approval of Oracle Corp's reported bid for TikTok, the Chinese video-sharing sensation that could also be bought by Microsoft.

Reports said Oracle - whose chairman Larry Ellison has raised millions in campaign funds for Trump - was weighing a bid for TikTok's operations in the US, Canada, Australia and New Zealand.

The Trump administration has given TikTok's parent company ByteDance a 90-day deadline to divest the app before it is banned in the United States, citing national security concerns.

Taking questions after a speech on Tuesday in Yuma, Arizona, Trump said: "I think Oracle is a great company, and I think its owner is a tremendous guy. He's a tremendous person.

"I think that Oracle would be certainly somebody that could handle it."

The president said the eventual buyer would have to "make sure the United States is well compensated."
