President Donald Trump said at a news conference said that the U.S. was getting a “fee plus” for brokering the sale of TikTok assets to an American buyer, adding that he personally uses the social media video app “very legitimately.”

The China-associated app has raised national security concerns, prompting a law requiring its owner ByteDance to sell TikTok’s U.S. operations or have the app banned. Trump has extended the ban deadline multiple times since January. Trump is slated to speak Friday with Chinese leader Xi Jinping.

Trump said that the assassinated conservative activist Charlie Kirk first encouraged him to get on TikTok.

“The United States is getting a tremendous fee plus,” said Trump, not defining what that term meant relative to the framework for a deal.
