Muhammed Ihsanullah was overjoyed when he received a $3,000 scholarship to spend the summer working at a camp in Minnesota.

But after several travelers from Western nations were detained or deported as part of the Trump administration’s crackdown on illegal immigration, the 20-year-old British citizen from Leicester, England, is planning on carrying a burner phone when he comes to the U.S. in May. That’s if he ends up going at all.

“I have a very, you know, stereotypical name as well,” Ihsanullah told NBC News. 

He might swap out devices, he said, “just so that I have the added security of knowing that no one’s going to go through my phone.”

Potential U.S. visitors such as Ihsanullah are expressing growing uncertainty about their travel plans amid the crackdown and warnings from U.S. embassies in more than a dozen countries, like the one in Sweden that said anyone entering the U.S. on a visa is a “guest” and if you lie about your intended behavior while in the country, “You’re out.”

Earlier this month, a Lebanese doctor working at Brown University’s medical center was sent home despite having a valid U.S. visa after U.S. Customs and Border Protection agents searching her phone found photos and videos they said were “sympathetic” to the former leader of the Hezbollah militant group, whose funeral she told agents she attended last month. 

Such searches pre-date the new Trump administration, and Customs and Border Protection says it conducts them to detect “digital contraband, terrorism-related content, and information relevant to visitor admissibility.”

“Claims that CBP is searching more electronic media due to administration change are false,” CBP Assistant Commissioner Hilton Beckham told NBC News in an emailed statement.

“Allegations that political beliefs trigger inspections or removals are baseless and irresponsible,” he added.

Such searches are not new to travelers from parts of the world who already face stringent visa requirements — Chinese students arriving in the U.S., for example, have complained in recent years of being increasingly subject to interrogation and detention on national security grounds. 

But many of the cases in recent weeks have involved travelers from countries such as France, Germany and Canada — longtime allies with which the U.S. shares intelligence, has frequent cultural exchanges and does hundreds of billions of dollars in trade. Several of those held have spoken out about being scrutinized and sometimes locked up for days at the border.

Last week, France’s interior minister said a French researcher had been turned away by U.S. border agents after they found messages on his phone criticizing the Trump administration. The CBP said searches of the researcher’s electronic media devices — they have not been named by the French authorities — led to the “discovery of proprietary information” from a U.S. laboratory.

CBP does not need a warrant to search the phones of any travelers arriving at the U.S. border, including airports, said Saira Hussain, a senior staff attorney at the Electronic Frontier Foundation, a nonprofit digital rights group based in San Francisco.

“The U.S. government has taken the view that they have the ability to search your devices without a warrant and without suspicion under what’s known as the border search exception to the Fourth Amendment,” she said.

Other travelers have found themselves unexpectedly detained.

Jasmine Mooney, a Canadian woman who was reapplying for a U.S. work visa, was detained without explanation on March 3 at the Mexican border near San Diego and spent 12 days in detention before returning home. She wrote in The Guardian that she was detained after she was questioned about the status of her visa, which had been granted following an initial rejection.

“There is no communication, you don’t have an officer to talk to,” Mooney told MSNBC last week. “You can’t contact your lawyers or your friends or your family.”

When Rebecca Burke, a backpacker from Britain, tried to enter from Canada in February, she spent nearly three weeks at a detention center. In a statement to the BBC, the Northwest ICE Processing Center said Burke was repatriated after being detained “related to the violation of the terms and conditions of her admission.”

Burke’s family said it believes her detention was due to a misunderstanding about her accommodation arrangements, which were free in exchange for helping hosts with household chores and which her father says authorities may have suspected constituted employment in violation of her visa.

And U.S. citizen Lennon Tyler said she was chained to a bench by border agents last month when her German fiancé, Lucas Sielaff, was accused of violating the rules of his 90-day U.S. tourist permit while trying to enter from Mexico. Sielaff was detained for two weeks before returning to Germany, according to The Associated Press.

Such incidents have prompted some governments to issue warnings for their citizens traveling to the U.S. The updated British travel advisory reads “you may be liable to arrest or detention if you break the rules.”

Those warnings have potential visitors to the U.S., like Pat Bastow, a Canadian citizen who plans to rent a car to visit Montana in July for a three-week holiday, seeking advice on how to protect themselves.

“A lot of travel agents are warning people not to go just in case Trump deports,” Bastow, a retired cattle farmer, told NBC News.

Hussain, the lawyer, said she is “encouraging people to think about uploading some of their data to the cloud and downloading it once you’re through screening.”

Turning phones off before arrival is also helpful, she said, as doing so disables facial recognition until a passcode is entered.

Travelers’ rights vary depending on their status — whether they are U.S. citizens, legal permanent residents or foreign visa holders — and their port of entry. Almost a quarter of the nearly 47,000 searches of electronic devices conducted at U.S. borders in the last financial year were of U.S. citizens, according to CBP data.

Hussain advised legal permanent residents, or green card holders, “who may have a bit of a complicated situation” to consult an attorney before traveling.

Visa holders who refuse a search of their devices could see their visas revoked and be barred from entering the U.S., she added.

Rules can vary across the country because the courts have largely avoided ruling on electronic device searches. Last year, a federal judge in New York barred CBP from warrantless searches of people’s phones, but that applies only to John F. Kennedy International Airport.

That lack of consistency, Hussain said, is “really why we believe that the Supreme Court needs to weigh in on this issue.”

Shareholders said in a complaint filed Monday that Chipotle “understated” diners’ dissatisfaction with “highly inconsistent (and in the view of some customers, lacking) portion sizes” in its risk disclosure in its 2023 annual report and 2024 first-quarter report. 

Customer grievances on social media escalated in the spring and summer months, according to the complaint, including one particular video from content creator Keith Lee, whose review of Chipotle—which included complaints of meager amounts of chicken in his burrito bowl—received 19.4 million views on TikTok.

The complaint cited Fortune’s coverage of Chipotle customers’ discontent following a May interview with CEO Brian Niccol, who was named as a defendant in the suit alongside John Hartung, chief financial and administrative officer. Niccol told Fortune portion sizes had not gotten smaller and touted the company’s generous portion sizes saying, “it’s kind of who we are.” Niccol left the restaurant chain to become the chief executive of Starbucks in September, and interim CEO Scott Boatwright replaced him as the company’s permanent head, Chipotle announced the same day the lawsuit was filed.

The complaint claimed Niccol’s statements were “materially false and misleading when made because portions had in fact gotten smaller in many cases.”

Niccol’s comments followed an outpouring of concern on social media that Chipotle was skimping on meat and rice, which sparked the viral trend of diners filming Chipotle staff making their orders to pressure them to pile on toppings. A Wells Fargo analysis in June validated customer complaints, showing that among 75 burrito bowls, there was vast variability in portion sizes, particularly for online orders, with the heaviest burrito bowl weighing 87% more than the lightest bowl.

“We don’t comment on litigation and will vigorously defend our industry leading real food,” chief corporate affairs officer Laurie Schalow told Fortune in an emailed statement.

The cost of beefing up portions

Niccol addressed customer concerns over portion sizes in a July 24 second-quarter earnings call, where he said more than 10% of Chipotle’s 3,500 locations had “outlier portion scores” and needed to retrain staff to make portions more consistent.

“There was never a directive to provide less to our customers,” Niccol said. “Generous portion is a core brand equity of Chipotle. It always has been, and it always will be.”

Chipotle’s recommitment to unsparing bowl sizes came at a price to the company. The company reported lower-than-expected revenue in last month’s third-quarter earnings due to expensive ingredients, as well as rectifying inconsistent portion sizes.

“The benefit of last year’s menu price increase was more than offset by inflation across several items, most notably avocados and dairy, as well as higher usage as we focused on ensuring consistent and generous portions,” chief financial officer Adam Rymer said in the earnings call.

Though foot traffic and same-store sales increased over the quarter, investors were less than impressed, and Chipotle’s stock fell nearly 8% following the earnings report. Ultimately, because Chipotle only later acknowledged the problem with its portions—and fixing the inconsistencies came at meaningful expense to the company and its shareholders—the chain’s true failure was the speed at which it disclosed its awareness of and addressed the problem, the lawsuit claims.

“As a result of Defendants’ wrongful acts and omissions, and the precipitous decline in the market value of the Company’s common shares,” the complaint said. “Plaintiff and other Class members have suffered significant losses and damages.”

The class-action lawsuit is seeking damages for those who bought or traded Chipotle stock or options between Feb. 8, 2024 and Oct. 29, 2024. The plaintiff claims hundreds or thousands of shareholders may be eligible.

After Perry Inhofe Sr. died in 1970, his children inherited interests in Mid-Continent Casualty, which their father had helped found. James and Perry Jr., became principals. In a stock trade in 1979, Perry Jr. acquired control of Mid-Continent and James acquired a spinoff, Quaker Life, which later failed. Lawsuits disrupted the family, and James won a $3 million settlement from Perry in 1990.

James, who became active in Oklahoma Republican politics in the mid-1960s, was a member of the State House of Representatives from 1967 to 1969 and of the State Senate from 1969 to 1977. He was a popular mayor of Tulsa, running unopposed for his second term and taking 59 percent of the votes for his third.

In 1986, when Representative James R. Jones, a Democrat, stepped aside to run for the Senate, Mr. Inhofe handily won his seat. In 1994, when Senator David Boren, a former Oklahoma governor, resigned in his third term to become president of the University of Oklahoma, Mr. Inhofe won the seat.

Mr. Inhofe’s exploits as one of the few licensed pilots in Congress attracted wide attention. He campaigned across Oklahoma in his private plane. In 1991, he and three other pilots flew a Cessna around the world in 18 days to commemorate the 60th anniversary of Wiley Post’s solo circumnavigation. He also claimed 11,000 hours of flying time.

In 2010, when he was 75, Mr. Inhofe landed his Cessna on a closed South Texas airport runway, scattering construction workers who ran for their lives. No one was hurt, but the construction supervisor and the airport manager reported the incident to the Federal Aviation Administration, and Mr. Inhofe was ordered to take four hours of remedial flying instruction in lieu of punishment.
