Supreme Court justices appeared to be skeptical toward TikTok's arguments when challenging a law that may result in it being banned.

The president-elect backed TikTok in a Truth Social post Friday as he tries to halt the law from taking effect.

U.S. Solicitor General Elizabeth Prelogar told the U.S. Supreme Court Friday that President-elect Donald Trump could ignore the ban of TikTok if he chooses.

WASHINGTON (AP) — The law that could ban TikTok is coming before the Supreme Court on Friday, with the justices largely holding the app’s fate in their hands. The popular social media platform says the law violates the First Amendment and should be struck down.

The Supreme Court seemed to lean Thursday toward upholding a law forcing Chinese parent company ByteDance to sell off TikTok, with all nine justices indicating national security concerns posed by the social media app outweighed potential threats to free speech.

TikTok has cemented itself as the quintessential entertainment app, offering everything from funny skits and makeup tutorials to social commentary and news.

WHATEVER ELSE YOU MIGHT SAY ABOUT HIM, Donald Trump does not lack ambition. For him, making vast, sweeping promises to solve every problem the country has ever faced comes as naturally as, well, lying. Here is a partial list of things he has promised to make happen “on Day One” of his second administration.

In 2020, he moved to ban the Chinese-owned app. Now, he is opposing the Biden administration’s effort to do just that.

Selling the app could be difficult, given its scale and nine-figure price. If TikTok’s parent company, the Chinese firm ByteDance, is forced to sell the app, who would buy it? ByteDance has said a sale is not feasible.

The Supreme Court seemed likely to uphold a new law that could force TikTok to shut down in the U.S., with conservative and liberal justices alike expressing skepticism about the legal challenge.

Justices will hear arguments in two consolidated cases taking aim at the federal law, which requires Chinese-owned ByteDance to divest from TikTok, or else TikTok will be banned from U.S. app stores and from being hosted by American internet service providers.

The Supreme Court is weighing if TikTok can be banned in the U.S. in a case pitting national security against free speech.
