On Sunday, former US President and presidential candidate Donald Trump created a verified account on the social media platform TikTok, which has already acquired over 1.5 million followers in less than 24 hours.

The account has only shared one brief video, which shows Trump visiting the latest Ultimate Fighting Championship event.

The prohibition on TikTok and WeChat was part of the Trump administration's long-running diplomatic and trade dispute with China before incumbent President Joe Biden's tenure began in January 2021.

TikTok, parent company ByteDance sue US government over ban

TikTok and its Chinese parent firm ByteDance launched a court challenge against the United States on Tuesday, targeting a regulation that would require the app to be sold or risk a US ban.

The legal action comes nearly two weeks after Joe Biden approved legislation allowing TikTok 270 days to find a non-Chinese buyer or risk a ban in the nation, something the platform alleges is unconstitutional.

The Senate voted to pass a bill that will either ban TikTok or force a sale of the app, giving its China-based parent company ByteDance up to one year to divest its crown jewel before being banned from US app stores.

The bill passed in the House with 79 senators voting in favor and 18 against, by a margin of 360 to 58, as part of a foreign aid package for Ukraine, Taiwan, and "Israel". It is now up to US President Joe Biden to make the final decision, noting that he previously said he would sign the legislation.

The petition by TikTok and ByteDance asserts that this is the first time Congress has enacted a law that subjects a "single named speech platform to a permanent, nationwide ban, and bars everyday American from participating in a unique online community with more than 1 billion people worldwide."

The petition alleged that the measure violates the First Amendment, claiming that "Congress has made a law curtailing massive amounts of protected speech."
