The US wants TikTok sold or banned because of alleged ties between ByteDance and the Chinese state, links that TikTok and ByteDance have always denied.
The bill introducing the law says it aims to “protect the national security of the United States from the threat posed by programs controlled by foreign adversaries.”
Trump opposes the ban – despite supporting the ban during his first term – in part on the grounds that it could help Facebook, which he has accused of helping to defeat him in the 2020 election.
Trump’s second term, however, will not begin until his inauguration on January 20, the day after the statutory deadline.
In its Supreme Court filing on Monday, TikTok asked for a “modest delay” in enforcing the ban to “create a breathing space” for the court to review and allow the new administration to “assess the matter.” .
He called TikTok “one of the most significant 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Earlier this month, the company bid to have the repealed injunction was dismissed by a federal appeals court, which found the law to be “the culmination of extensive bipartisan action by Congress and successive presidents.”
