• The Supreme Court ruled against TikTok on its challenge against a divest-or-ban law.
• TikTok's owner ByteDance has until January 19 to divest from its US app or face a shutdown.
• President-elect Donald Trump may still try to rescue the app once in office.

The Supreme Court decided not to rescue TikTok from a divest-or-ban law.

The justices said on Friday that the law does not violate the First Amendment rights of TikTok and its creators.

As a result, TikTok is likely to "go dark" in the US on January 19 as app stores and other business partners sever ties with the company to comply with the law.

TikTok may also voluntarily shut down its app in the US on Sunday, The Information and Reuters reported earlier this week. TikTok has declined to comment on its plans.

The company on Tuesday sent a memo to US employees reassuring them that they would still have jobs even if the app gets banned.

The Supreme Court's decision was expected. Legal analysts told Business Insider last week that the court was likely to rule against TikTok in deference to Congress' authority over national-security concerns.

Speaking before Friday's decision, Neama Rahmani, a formal federal prosecutor in California, told BI that he expected the Supreme Court to uphold the law.

He described how, at last week's hearing, Chief Justice John Roberts and Justice Brett Kavanaugh, appointed by Republican presidents, were "talking about the national security concerns."

"Even Kagan was skeptical. When you have a conservative majority that's focused on the national security concerns, it does seem like the law will be upheld," Rahmani said.

TikTok's appeal arrived in the Supreme Court after it lost its legal challenge to the divest-or-ban law in the DC Circuit in December.

TikTok was a primary target of The Protecting Americans from Foreign Adversary Controlled Applications Act, which passed in April and sought to curb the influence of social platforms with foreign-adversary owners.

Having worn out its legal options, TikTok may be banking on a different path to survival: the return of President-elect Donald Trump, who will be inaugurated on Monday. TikTok's CEO Shou Chew plans to attend the inauguration alongside other tech CEOs.

Trump pledged to try to save TikTok once in office, saying during a December 16 press conference that he had "a warm spot in my heart for TikTok." On December 27, he filed an amicus brief to the Supreme Court, asking for a stay on TikTok's divestment deadline so he could work out a political resolution.

"President Trump opposes banning TikTok in the United States at this juncture, and seeks the ability to resolve the issues at hand through political means once he takes office," the brief said.

• I tried classic tuna sandwiches at Subway, Jimmy John's, and Jersey Mike's to find the best one.
• Subway and Jersey Mike's both had OK offerings, but there were problems with both.
• Jimmy John's sandwich had a great balance of ingredients and spot-on taste and texture.

I think ordering a tuna sub is always going to be a bit of a risk. Will the fish taste fresh enough? Will the mayo be slapped on too heavily? Will the whole sandwich be a mess?

However, I've already found the best club sandwiches and best roast-beef subs to order, so in the name of research, I got tuna at Jimmy John's, Jersey Mike's, and Subway to see which popular chain comes out on top.

I made the sandwiches as similar as possible, starting with each chain's default bread stacked with a tuna blend, mayo, lettuce, and tomatoes. Subway and Jimmy John's sandwiches also had cucumber slices, which weren't available at Jersey Mike's.

Once home, I unwrapped each sandwich, wrote down some first impressions, and got on with the comparison.

I started my taste test at Subway.

Subway isn't everyone's first choice for a sandwich. However, it's a global chain with tens of thousands of locations, so I find myself there quite a bit — especially when I'm traveling.

I ordered a 6-inch tuna sub for $6.49.

Subway tuna was in the press in 2021 when a lawsuit alleged that the product didn't contain any real tuna fish. It was later dismissed, and there's now a page on the Subway website dedicated to talking about its tuna.

Subway's tuna sandwich was inoffensive but unmemorable.

The best thing I can say about the tuna sandwich I got from Subway was that it wasn't bad.

I found the sandwich and its main ingredient inoffensive. Sadly, though, none of the flavors really stood out.

I liked the addition of cucumber, but even with those, there wasn't much contrasting texture to speak of, either.

The chain had more toppings and condiments available than the others, but I had to keep the playing field level. So, the six-ingredient sandwich I took home was a decent but hardly laudable concoction.

On the plus side, it was assembled with decent care and wasn't a mess to eat.

Jersey Mike's usually impresses me, so I had high hopes.

Jersey Mike's is a New Jersey-based sandwich chain that opened in the 1950s.

Since then, the shop has made a pretty big name for itself — I can't be the only one inundated with its many commercials featuring Danny DeVito. Today, there are more than 2,000 locations across the US and Canada.

My regular (7-inch) No. 10 tuna sandwich cost $9.65

I was glad I was alone when eating this messy sub.

Pro tip: Don't eat a tuna sandwich from Jersey Mike's on a first date. I mean, no tuna sandwiches from anywhere on early dates, but especially not this one.

If your Jersey Mike's tuna-sub experience is anything like mine, it's going to be an absolute mess. Given that this isn't the first time I got a massively overfilled sandwich at the chain, though, I'm afraid it's the norm.

You may get a lot of bang for your buck, but right from the moment I unwrapped the sandwich, bits of tuna and finely shredded lettuce fell from the sides. The sub was slippery and hard to keep together with each bite.

To be clear, it tasted great. I missed the crunch of the cucumber the other two had, but the fish's flavor profile was the best of the bunch here.

Unfortunately, it's hard to overlook the unpleasant eating experience.

Finally, I swung by Jimmy John's for a sub.

Like Jersey Mike's, Jimmy John's is a North American sandwich chain with over 2,000 locations across the US and Canada.

It's known for its fresh-baked bread — which I'm a huge fan of.

I ordered a No. 3 "totally tuna" sandwich for $9.49. Jimmy John's standard size is 8 inches, making it the longest sub of the bunch.

Jimmy John's tuna sandwich was tasty and tidy.

If you've read any of my past sandwich reviews, you've heard me rave about the delicious French bread at Jimmy John's. I won't dwell on it again but just know that it's reliably excellent.

Now, on to the sandwich as a whole.

For one thing, it stayed together. In fact, it was so well-made that I could eat it with one hand without anything falling out.

The flavor of the fish was mild but pleasant, and the veggies were fresh and crisp. Overall, the sandwich had a great taste and texture.

None of the sandwiches were awful, but one tuna sub reigned supreme.

I don't eat tuna sandwiches often enough to risk a negative experience, so the next time I crave one, I'll play it safe and return to Jimmy John's.

My sub there was pretty much perfectly made, and it had all the right flavors going on.

If the tasty sandwich from Jersey Mike's wasn't such a mess, it may have been my favorite. However, as it is, I doubt I'll order it again anytime soon.

Subway's offering wasn't necessarily bad, but the flavor just wasn't there. I wouldn't choose it over either of the other two.

The adorable Bauhn mini retro speaker is a Bluetooth-compatible device that's both rechargeable and portable.

The Supreme Court on Friday upheld a law that could ban TikTok in the U.S.

The big picture: The court unanimously rejected TikTok's claims that the law violates the First Amendment.

• The wildly popular app was on course to disappear for U.S. users as soon as Sunday But President-elect Trump has said he would delay enforcement of that ban. TikTok's long-term future is still unclear.

Driving the news: The bipartisan law President Biden signed in April requires ByteDance, TikTok's Chinese parent company, to either sell TikTok or shutter it inside the U.S. on Jan. 19.

• The justices said that because the primary responsibility falls on a foreign company, and because all of the speech that's currently on TikTok could still be there under new ownership, the First Amendment does not apply.

What's next: Trump had asked the court not to let the ban take effect as scheduled, one day before his inauguration.

• Finding a way to keep TikTok alive may not seem like an emergency, but the app's sheer popularity will make it a top concern in the early days of Trump's new term.
• Only a few potential buyers could put together enough money to even make a serious offer for the dominant social-media platform. Bloomberg reported that the Chinese government was considering selling TikTok to Elon Musk, though ByteDance flatly denied that.
• But all sale discussions are in their early stages — in the months since the law took effect, ByteDance and TikTok have been more focused on avoiding the Jan. 19 deadline than finding a way to comply with it.

President-elect Trump spoke Friday with Chinese President Xi Jinping by phone just days before the U.S. presidential inauguration.

Why it matters: Trump said last month he exchanged messages with Xi after winning the election but didn't confirm they spoke. The president-elect has promised to implement aggressive tariffs on imports from China and could also be forced to determine the fate of TikTok upon taking office.

• The call took place several hours after the Chinese foreign ministry announced that Xi is sending his vice president Han Zheng to Washington, D.C., to attend the inaugural ceremony Monday.
• President Biden has said he won't enforce the TikTok ban that's supposed to take effect Sunday, the AP reported.

What they're saying: "I just spoke to Chairman Xi Jinping of China. The call was a very good one for both China and the U.S.A. It is my expectation that we will solve many problems together, and starting immediately," Trump said in a post on his truth Social account.

• He said they discussed balancing trade, fentanyl, TikTok and "many other subjects".
• "President Xi and I will do everything possible to make the World more peaceful and safe!", Trump added.

State of play: According to a bipartisan law passed last year, the Chinese-owned TikTok needs to be sold to an American company or shut down operations in the U.S. by Jan. 19, due to national security concerns.

• Trump has said he wants to take measures to "preserve" the wildly popular app in the U.S. despite the new law, his incoming national security adviser, Rep. Michael Waltz (R-Fla.), said Thursday.
• Trump asked the Supreme Court last month to pause the TikTok ban, cementing his flip-flopping after he advocated to ban the app during his first term.
• The high court is set to rule as soon as Friday on whether to uphold the law, which justices seemed inclined to do during oral arguments last week.
