Oracle is considering buying part of the assets of the popular service TikTok.

TikTok may be blocked in the United States if it continues to be owned by China’s ByteDance. Oracle is currently in talks with other potential TikTok buyers for a possible joint purchase, including investment firm Sequoia. For now, Oracle may push Microsoft, the only potential buyer, to confirm its intentions publicly.

The owner of Oracle is the only Silicon Valley tycoon who openly supports Donald Trump. Billionaire Larry Allison raised funds for the incumbent president on his own estate.
