Cashier is the second largest occupation in America, with more than 3 million people holding the job in 2013. It soon might be a job of the past, though, as Microsoft is working on technology that would automate checkout lines in order to help businesses compete with Amazon, Reuters reports.

Earlier this year, Amazon opened its first brick-and-mortar grocery store, which introduced cashier-free shopping. Customers scan a smartphone app linked to a credit card when they pass through a turnstile to get into the store, then cameras and weight sensors on shelves determine what they buy. To help keep other businesses competitive as Amazon expands, Microsoft is testing its own system that would track what people add to their carts, while also attempting to keep the technology inexpensive enough that grocery stores and other retailers can afford to use it.

"This is the future of checking out for convenience and grocery stores," Gene Munster, the head of research at Loup Ventures, told Reuters. Loop Ventures estimates the automated checkout market in the United States is worth some $50 billion. Jeva Lange

Moscow on Sunday pushed back against President Trump's Sunday night announcement that he intends to withdraw from the Intermediate-Range Nuclear Forces Treaty, an arms control agreement with Russia that dates to the Reagan era.

"This would be a very dangerous step," said Russia Deputy Foreign Minister Sergei Ryabkov, as quoted in Russian state media. He argued the announcement is like "blackmail" ahead of National Security Adviser John Bolton's planned trip to Russia this coming week.

"Unlike our American colleagues, we understand all the seriousness of the issue and its significance for security and strategic stability," Ryabkov continued. "If the Americans continue to act as crudely  ... and unilaterally withdraw from all sorts of agreements and mechanisms, from the Iran deal to the International Postal treaty, then we'll be reduced to taking action in response, including of a military nature. But we don't want to go that far."

Trump has argued with NATO support that Russian missile tests conducted in the last decade violate the terms of the treaty. "And we're not going to let them violate a nuclear agreement and go out and do weapons and we're not allowed to," he said Sunday. Bonnie Kristian

A coalition of human rights and journalism groups including Amnesty International, the Committee to Protect Journalists, Human Rights Watch, and Reporters Without Borders on Sunday called for Turkey to instigate a United Nations investigation into the death of Saudi journalist Jamal Khashoggi at the Saudi consulate in Istanbul.

"U.N. involvement is the best guarantee against a Saudi whitewash or attempts by other governments to sweep the issue under the carpet to preserve lucrative business ties with Riyadh," said Robert Mahoney of the Committee to Protect Journalists. The business ties Mahoney has in mind are likely a major U.S.-Saudi arms deal President Trump has refused to cancel regardless of what happened to Khashoggi.

U.N. Secretary-General Antonio Guterres has already stressed the "need for a prompt, thorough, and transparent investigation into the circumstances of Mr. Khashoggi's death and full accountability for those responsible."

After denying knowledge of Khashoggi's whereabouts for two weeks, Saudi Arabia on Saturday said he died in "a brawl and a fist fight" inside the consulate. However, an unnamed senior Saudi official on Sunday told Reuters a 15-man team "overstepped their orders and quickly employed violence," in Reuters' paraphrase, accidentally killing him with a chokehold intended to smother his shouts.

At least 18 people were killed and about 160 injured when a passenger train derailed in Taiwan on Sunday evening local time. The train was carrying 366 people, and rescue efforts continue as several dozen were trapped on board. The line runs in a coastal area and is popular with tourists; an American woman was among those hurt.

Taiwanese President Tsai Ing-wen pledged "all our strength and efforts for the rescue" in a Facebook post offering condolences for the families of the victims and cautioning against speculation as to the cause of the crash while the investigation is underway. Bonnie Kristian

Afghanistan's parliamentary election was extended for a second day Sunday after Saturday's voting was marred by violence, technical difficulties and, in some places, polling stations that did not open at all.

This is the first such election since 2010, and it employs a biometric tracking system to avoid fraud that has not been widely tested. "More than 25 percent of the [voting] centers we observed were not opened," reported Naeem Ayubzada of Transparent Election Foundation of Afghanistan. "We also observed technical challenges with 32 percent of the biometric systems not working in 22 percent of the polling centres. Also, 9 percent of the centers were not equipped with the biometric system."

The Taliban, which remains powerful particularly in rural regions, has told Afghanistan's 8.8 million eligible voters to stay away from the polls, but despite these obstacles, more than 3 million voted Saturday. Bonnie Kristian

President Trump said Saturday he is reviewing a list of five candidates to replace outgoing U.S. Ambassador to the United Nations Nikki Haley, and he expects to announce a decision soon. "We'll have somebody great," the president pledged. "We're going to pick somebody very quickly."

Two of the candidates are men, and three are women, Trump said, telling reporters he "might prefer" to have a woman in the role. "I think it's become maybe a more glamorous position than it was two years ago," he said. "Maybe, I wonder why, but it is. [Haley has] made it a very glamorous position."

Haley's next step remains unknown, as she has insisted she will not run for the presidency in 2020. Bonnie Kristian

President Trump said at a campaign rally in Nevada Saturday his administration is working on new tax cuts for the middle class and expects to reveal the plan before the midterms.

"We are going to be putting in and are studying very deeply right now, around the clock, a major tax cut for middle-income people," he said. "Not for business at all. For middle-income people." He described the timeline for the new cuts, as promised in May, as "sometime just prior, I would say, to November."

Congress is in recess until after the midterm elections and cannot pass any new tax law before November begins. Last December, Trump signed into law the largest tax reform bill since the 1980s. Bonnie Kristian
