President-elect Donald Trump met with TikTok CEO Shou Chew at Mar-a-Lago on Monday.

The wildly popular social media app is set to be banned nationwide on January 19, one day before Trump takes office, unless it is sold to a new non-Chinese owner.

CNN reports:

President-elect Donald Trump met with the head of TikTok at his Mar-a-Lago club Monday afternoon, a person familiar with the meeting told CNN, as the social media giant is asking the Supreme Court to wade into a court fight over use of the app in the United States.

The pre-scheduled meeting with TikTok CEO Shou Chew is believed to be the first time the men have met since Trump's electoral victory in November, another person told CNN. Chew, who was seen at Trump's Florida resort in early December, has been trying to meet with Trump since he was elected, and is just the latest meeting the president-elect is holding with top executives from some of America's largest tech companies.
