WASHINGTON — U.S. health regulators posted a positive review of Pfizer's COVID-19 vaccine as they near a decision on whether to allow use of the shot. The review posted online Tuesday by the Food and Drug Administration offers the world the first detailed look at the evidence behind the shot, which was co-developed with BioNTech. The FDA review comes before a Thursday meeting where a panel of independent experts will scrutinize the data and vote on whether to recommend use of the vaccine.The vote isn't binding but the FDA usually follows the group's guidance. A U.S. decision to allow use of the vaccine is expected within days. 642

WASHINGTON (AP) — Human feces, overflowing garbage, illegal off-roading and other damaging behavior in fragile areas were beginning to overwhelm some of the West's iconic national parks, as a partial government shutdown left the areas open to visitors but with little staff on duty."It's a free-for-all," Dakota Snider, 24, who lives and works in Yosemite Valley, said by telephone Monday, as Yosemite National Park officials announced closings of some minimally supervised campgrounds and public areas within the park that are overwhelmed."It's so heartbreaking. There is more trash and human waste and disregard for the rules than I've seen in my four years living here," Snider said.The partial federal government shutdown, now into its 11th day, has forced furloughs of hundreds of thousands of federal government employees. This has left many parks without most of the rangers and others who staff campgrounds and otherwise keep parks running.Unlike shutdowns in some previous administrations, the Trump administration was leaving parks open to visitors despite the staff furloughs, said John Garder, senior budget director of the nonprofit National Parks Conservation Association."We're afraid that we're going to start seeing significant damage to the natural resources in parks and potentially to historic and other cultural artifacts," Garder said. "We're concerned there'll be impacts to visitors' safety.""It's really a nightmare scenario," Garder said.Under the park service's shutdown plan, authorities have to close any area where garbage or other problems become threats to health and safety or to wildlife, spokesman Jeremy Barnum said in an email Monday."At the superintendent's discretion, parks may close grounds/areas with sensitive natural, cultural, historic, or archaeological resources vulnerable to destruction, looting, or other damage that cannot be adequately protected by the excepted law enforcement staff that remain on duty," Barnum said.In the southern Sierra Nevada in Central California, some areas of the Sequoia and Kings Canyon national parks were closed Monday evening. In Sequoia, home to immense and ancient giant sequoias, General Highway was closed because overflowing trash bins were spreading litter and posed a threat to wildlife and the icy, jammed roadway was seeing up to three-hour delays, according to the National Park Service.Also closed was the Grant Tree Trail, a popular hiking spot, because the government shutdown halted maintenance and left the path dangerously slick from ice and snow, with at least one injury reported, the park service said.Campers at Joshua Tree National Park in Southern California's deserts were reporting squabbles as different families laid claims to sites, with no rangers on hand to adjudicate, said Ethan Feltges, who operates the Coyote Corner gift shop outside Joshua Tree.Feltges and other business owners around Joshua Tree had stepped into the gap as much as possible, hauling trailers into the park to empty overflowing trash bins and sweeping and stocking restrooms that were still open, Feltges said.Feltges himself had set up a portable toilet at his store to help the visitors still streaming in and out of the park. He was spending his days standing outside his store, offering tips about the park in place of the rangers who normally would be present."The whole community has come together," Feltges said, also by phone. "Everyone loves the park. And there's a lot of businesses that actually need the park."Some visitors have strung Christmas lights in the twisting Joshua trees, many of which are hundreds of years old, the Los Angeles Times reported.Most visitors were being respectful of the desert wilderness and park facilities, Joshua Tree's superintendent, David Smith, said in a statement.But some are seizing on the shortage of park staffers to off-road illegally and otherwise damage the park, as well as relieving themselves in the open, a park statement said. Joshua Tree said it would begin closing some campgrounds for all but day use.At Yosemite, Snider, the local resident, said crowds of visitors were driving into the park to take advantage of free admission, with only a few park rangers working and a limited number of restrooms open.Visitors were allowing their dogs to run off-leash in an area rich with bears and other wildlife, and scattering bags of garbage along the roads, Snider said."You're looking at Yosemite Falls and in front of you is plastic bottles and trash bags," he said.Officials at Rocky Mountain National Park in Colorado said Monday they were closing restrooms and locking up trash bins in many locations.In Yellowstone National Park, private companies have picked up some of the maintenance normally done by federal workers. The contractors that operate park tours by snowmobile, buses and vans are grooming trails, hauling trash and replacing toilet paper at pit toilets and restrooms along their routes.Nearly all roads inside Yellowstone are normally closed for winter, meaning most visitors at this time of the year access park attractions like Old Faithful or the Grand Canyon of the Yellowstone through guides. Those guides are splitting the cost of grooming the trails used by their vehicles to keep their operations going, said Travis Watt, general manager of See Yellowstone Alpen Guides based in West Yellowstone, Montana.The tour companies can likely keep this system going through the entire winter season if they need to, Watt said."It's definitely not our preference — the park service does a good job doing their thing and we hate to see them out of work," Watt said. "But it's something we can handle."___Gecker reported from San Francisco. Matt Volz contributed from Helena, Montana. 5752

WASHINGTON (AP) — In her Republican National Convention speech, Kimberly Guilfoyle described herself as a first-generation American, citing her mother's Puerto Rican roots.But Puerto Rico is a U.S. territory, and its residents are U.S. citizens.Guilfoyle, a Trump campaign adviser and the girlfriend of Donald Trump Jr., cited her family history on Monday to make the case that she knows how dangerous a socialist agenda would be for the nation.She says her mother was a special education teacher from Aguadilla, Puerto Rico, while her father, whom she described as “also an immigrant, came to this nation in pursuit of the American dream.” Her father is from Ireland.Now, she says, “I consider it my duty to protect that dream.”The Trump campaign did not immediately respond to a request for clarification. 815

Volunteers at a Chicago food bank got a surprise treat for the holidays.Former President Barack Obama paid an unannounced visit Tuesday to the Greater Chicago Food Depository, where he helped bag potatoes for Thanksgiving meals.Wearing a Chicago White Sox hat, Obama arrived with bags of donated food and donned latex gloves to work side by side with volunteers at the nonprofit, which helps provide meals to more than 700 food pantries and shelters across Cook County, Illinois.The former President and longtime Chicago resident came with staffers from the Obama Foundation, which seeks to improve communities across the US through leadership training and other educational efforts."Hey, how's it going?" he asked volunteers as he walked in. "This is a spiffy-looking spot right here.""We believe no one should go hungry, especially this time of year, and that's why we're working to address the root causes of hunger in Chicago and Cook County," the food bank tweeted out Tuesday, along with a video of the surprise visit.In the video, Obama encounters two little girls who are volunteering and tells them, "You guys are doing such a great job helping out. I'm really proud of you."Obama still lives in Washington but was in Chicago to attend the Obama Foundation Summit, a gathering of community leaders and students.A hallmark of Obama's presidency was combating hunger across the globe. In 2009, his administration pledged?.5 billion over three years to a Feed the Future initiative, which works to promote agricultural knowledge and tools in areas with high food insecurity. In 2016, he signed the Global Food Security Act to bolster government efforts toward Feed the Future initiatives.This was not the first time Obama has volunteered during the Thanksgiving holiday. He and his family spent the day before Thanksgiving in 2015 serving dinner to homeless people and veterans at Friendship Place Homeless Center in Washington.Back then, Obama said it wasn't only "of the spirit of giving during this holiday season but our national obligation to make sure all those who serve and sacrifice for our country have a place to call home." 2176
