TikTok on Sunday restored service to users in the United States after a brief shutdown after President-elect Donald Trump vowed to issue an executive order temporarily allowing the social media app to keep operating despite a law banning it as long as it is Chinese controlled.

"We thank President Trump for providing the necessary clarity and assurance to our service providers that they will face no penalties providing TikTok to over 170 million Americans and allowing over 7 million small businesses to thrive," TikTok said in a statement.

"It's a strong stand for the First Amendment and against arbitrary censorship,” it added. “We will work with President Trump on a long-term solution that keeps TikTok in the United States."

Trump had announced earlier Sunday on Truth Social that he plans to issue an executive order extending the length of time for TikTok to comply with the law that forces its parent company, ByteDance, to sell the app to a U.S. entity or face a ban.

TikTok went dark on Saturday night but began roaring back to life around midday Sunday.

Trump had said on Saturday he was considering a 90-day extension for TikTok.

"I’m asking companies not to let TikTok stay dark! I will issue an executive order on Monday to extend the period of time before the law’s prohibitions take effect, so that we can make a deal to protect our national security," he wrote on Sunday. "The order will also confirm that there will be no liability for any company that helped keep TikTok from going dark before my order."
 
Trump also said that Americans "deserve to see our exciting inauguration on Monday" as well as other events.
 
"I would like the United States to have a 50% ownership position in a joint venture.  By doing this, we save TikTok, keep it in good hands and allow it to say up.  Without U.S. approval, there is no Tik Tok.  With our approval, it is worth hundreds of billions of dollars - maybe trillions," he said.
