DOVER AIR FORCE BASE, Del. (AP) — The Latest on President Donald Trump's trip to Dover Air Force Base (all times local):

Forensic experts filled body bags with charred human remains in the field where the explosion occurred on Friday evening by the town of Tlahuelilpan in the state of Hidalgo, in one of the deadliest incidents to hit Mexico's troubled oil infrastructure in years. A number of people at the scene told Reuters that local shortages in gasoline supply since Lopez Obrador launched a drive to stamp out fuel theft had encouraged the rush to the gushing pipeline. "Everyone came to see if they could get a bit of gasoline for their car, there isn't any in the gas stations," said farmer Isaias Garcia, 50.

Airlines are already canceling flights ahead of a new winter storm forecast to bring snow and ice from the Great Plains to the Midwest and Northeast.

Stock markets across the globe powered higher Friday, buoyed by hopes of a breakthrough in efforts to defuse a US-China trade war.

While the debate over immigration and a border wall between the United States and Mexico has helped grind the U.S. federal government to a halt, Mexico's national airline, AeroMexico, is trolling Americans with a new ad called "DNA Discounts." The ad features purported residents of Wharton, Texas, a town about 60 miles southwest of Houston, professing a variety of opinions about Mexico and its citizens. The ad also drops some knowledge about the long history of immigration from Mexico to the U.S., and notes that many in southern and southwestern states have a touch of Mexican DNA. Things get flipped when the airline reveals it's offering flight discounts to Americans, including those Wharton residents, based on the amount of Mexican DNA they have (i.e., 18 percent DNA equals an 18 percent discount). That certainly turns opinions around. As one recipient says, "I love discounts!" Of course, it's such a brilliant ad, it's hard to tell if those Wharton residents are real or just actors and if this whole DNA discount thing is real  or satirical. Aeromexico, which has gotten political before, isn't saying much, but we've reached out for comment and will update this post when we hear back.  Either way, it's a brilliant gambit that undermines the vitriol so many Americans have expressed at our neighbors to the south, and does so without ever directly mentioning the political turmoil, the wall, or even President Trump. Instead, it directs that energy at a sense of shared community, including the tagline, "There are no borders within us." Not a bad way to spread a powerful message.

Treasury Secretary Steven Mnuchin is a proponent of easing up on tariffs, while U.S. Trade Representative Robert Lighthizer has reservations about the idea, the newspaper reported Thursday, citing unnamed people close to the discussions. The Treasury Department disputed that reporting. Neither Mnuchin nor Lighthizer has made any recommendations with respect to tariffs or other parts of the negotiations with China, according to a Treasury spokesperson working with the administration’s trade team who characterized the talks as an ongoing process.

The students from private, all-male Covington Catholic High School in northern Kentucky were in Washington for an anti-abortion rally on Friday when they were filmed surrounding Nathan Phillips and mocking the Native American's singing and drumming. Fellow students, many in clothing bearing President Donald Trump's "MAGA" slogan, cheered him on and chanted, "build that wall, build that wall," Phillips said.

The Weather Service issued winter storm warnings or advisories for a swath of the eastern United States that is home to 100 million people, said meteorologist Rich Otto of the U.S. Weather Prediction Center. The storm system, which was moving from west to east and was strengthened by arctic air from Canada, hit many parts of the Midwest on Friday, according to the National Weather Service. In Chicago, where some neighborhoods received 8 inches (20 cm) of snow, a third of flights were canceled at the city's two main airports, said Mark Duell, vice president of operations for tracking firm FlightAware.

U.S. Senator Kirsten Gillibrand made her maiden voyage to the critical primary state of Iowa over the weekend, laying out her case that she is the best Democrat to challenge President Donald Trump in the U.S. presidential election in 2020. Gillibrand, from New York, joins a small field of Democratic contenders that is expected to expand by over a dozen more, all vying for the party's nomination and the right to challenge Trump, if he is the Republican's 2020 nominee. Criticized in the past by party left-wingers as too moderate, Gillibrand repeatedly emphaxxxxd her support for a "Medicare for all" proposal to create a national health care system.

Negotiators for 30,000 striking Los Angeles teachers and America's second-largest school district returned to the bargaining table on Saturday for a third day of contract talks mediated by the mayor, as educators took a weekend break from picket lines. Teachers staging the first strike against the Los Angeles Unified District in 30 years were pressing demands for higher pay, smaller class xxxxs and expanded support staff. School district Superintendent Austin Beutner said on Friday he was determined to clinch a deal in time for teachers to return to the job on Tuesday, avoiding a second week of disrupted classes for nearly 500,000 students.

Women's March, a national nonprofit organization that evolved from the initial Washington march, again hosted its main event in Washington, with hundreds of "sister" marches in other cities. "There is definitely huge, huge focus on the 2020 elections," said March On's Natalie Sanchez, an organizer of the 2017 Boston Women's March who is also with March Forward Massachusetts, which organized Saturday's march there. U.S. Senator Kirsten Gillibrand, who launched her bid for the 2020 Democratic presidential nomination this week, addressed the women's march in Des Moines, Iowa, the state that holds the first nominating contest and acts as a proving ground for White House hopefuls.

Trump, locked in a battle with congressional Democrats that has led to a nearly month-long partial government shutdown, announced his trip via a pre-dawn tweet, saying he was going "to be with the families of 4 very special people who lost their lives in service to our Country!" Trump told reporters on the South Lawn of the White House prior to departure that he planned to meet the families, a duty which he said "might be the toughest thing I have to do as president." He was greeted by military staff at Dover Air Force Base after a short flight from Joint Base Andrews, but did not speak to reporters before entering his motorcade. Flanked by military officials, Trump, Secretary of State Mike Pompeo and acting Defense Secretary Patrick Shanahan filed up a ramp leading onto a military transport aircraft, where a prayer was given to honor the memory of Scott Wirtz, a civilian Department of Defense employee from St. Louis.

The episode, which followed years of tight budgets that left little money for medical staff, highlights the potential impact of a lack of nurses throughout the Los Angeles Unified School District, one of the key reasons Escobedo and her colleagues are on strike. In L.A., as in many districts across the United States, the school nurse is the first and sometimes only point of entry for many families into a complicated and expensive health-care system. Like most schools in the more than 1,200-campus district, Lockwood Elementary, where Escobedo teaches, has a nurse just once a week.
