US President Donald Trump is meeting with the CEO of TikTok as the social media giant fights plans to ban it in the US.

Trump was due to meet with Shou Chew at his Mar-a-Lago estate in Florida on Monday, the BBC's US partner CBS News reports, citing sources familiar with the meeting.

A law passed earlier this year means Tiktok will be banned if it is not sold by its Chinese parent company, ByteDance, by January 19.

The company has made an urgent request to the US Supreme Court to delay the ban.

The US wants TikTok to be sold or banned because of alleged links between ByteDance and the Chinese state, links that both TikTok and ByteDance have denied.

The bill that introduced the law said it was intended to "protect the national security of the United States from the threat of claims controlled by foreign adversaries."

Trump opposes the ban - despite supporting one in his first term - in part because it could help Facebook, which he accuses of aiding the loss his 2020 election.

Trump's second term, however, will not begin until his inauguration on January 20, the day after the date specified in the law.

In its appeal to the Supreme Court, which was submitted on Monday, TikTok asked for a "slight delay" in the implementation of the ban to "create breathing room" for a review by the Court and allow the incoming administration to "assess this matter".

He described TikTok as "one of the most important speech platforms" in the US and said the ban would cause "immediate and irreparable harm" to the company and its users.

Earlier this month, the company's application became available the suspension was denied by the federal appeals court, which found the law to be "the culmination of extensive, bipartisan action by Congress and successive presidents".

At a press conference on Monday, Trump said his administration would "take a look at TikTok".

"I have a warm place in my heart for TikTok, because I won junior with 34 points," he said.

"There are those who say that TikTok has something to do with that. TikTok had an effect."

A majority of 18- to 29-year-olds supported Trump's Democratic challenger, Kamala Harris, in November, but the poll saw a significant shift toward Trump among younger voters since the 2020 election.

Trump it only joined TikTok in Junebut he gained millions of followers on stage during the campaign.
