After nearly three hours of Supreme Court arguments Friday morning, Americans are one step closer to learning whether a TikTok ban will take effect in nine days.

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.

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 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.

Law professor Stephen Vladeck has said Trump's bid to delay a law targeting TikTok could damage the relationship between the presidency and the Supreme Court.

President-elect Donald Trump filed a brief with the court last month, urging the bench to pass on ruling on the ban until he takes office, when his lawyers argue he could “pursue a political resolution that could obviate the Court’s need to decide these constitutionally significant questions.”

The Supreme Court seems likely to uphold a law that would ban TikTok in the United States beginning Jan. 19 unless the popular social media program is sold by its China-based parent company.

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