WASHINGTON — In an official update on his health status since contracting COVID-19, President Donald Trump told his personal physician “I feel great” Wednesday morning.In a statement shared on Twitter, Dr. Sean Conley also said the president’s vital signs remain “stable and in the normal range.” He added that Trump has not had a fever in more than four days and has not needed “supplemental oxygen since initial hospitalization.”Meanwhile, the president is remaining inside the White House as he recovers and has no public events scheduled Wednesday. Aides are being told to take extensive precautions to prevent themselves from catching the coronavirus. 664

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) — A major union representing U.S. postal workers endorsed Democrat Joe Biden, a move that comes after President Donald Trump acknowledged he was starving the postal service of money in order to make it more difficult to vote by mail in November’s election. The National Association of Letter Carriers, which represents 300,000 current and retired workers, said Thursday that Trump's longstanding hostility to the mail-delivering agency has heightened during the pandemic. They say his administration has taken “steps outside of the public eye to undermine the Postal Service and letter carriers." Union president Fredric Rolando said Biden is a "fierce ally and defender of the United States Postal Service." 732

  

WASHINGTON (AP) — Behind America's late leap into orbit and triumphant small step on the moon was the agile mind and guts-of-steel of Chris Kraft, making split-second decisions that propelled the nation to once unimaginable heights.Kraft, the creator and longtime leader of NASA's Mission Control, died Monday in Houston, just two days after the 50th anniversary of what was his and NASA's crowning achievement: Apollo 11's moon landing. He was 95.Christopher Columbus Kraft Jr. never flew in space, but "held the success or failure of American human spaceflight in his hands," Neil Armstrong, the first man-on-the-moon, told The Associated Press in 2011.Kraft founded Mission Control and created the job of flight director — later comparing it to an orchestra conductor — and established how flights would be run as the space race between the U.S. and Soviets heated up. The legendary engineer served as flight director for all of the one-man Mercury flights and seven of the two-man Gemini flights, helped design the Apollo missions that took 12 Americans to the moon from 1969 to 1972 and later served as director of the Johnson Space Center until 1982, overseeing the beginning of the era of the space shuttle.Armstrong once called him "the man who was the 'Control' in Mission Control.""From the moment the mission starts until the moment the crew is safe on board a recovery ship, I'm in charge," Kraft wrote in his 2002 book "Flight: My Life in Mission Control.""No one can overrule me. ... They can fire me after it's over. But while the mission is under way, I'm Flight. And Flight is God."NASA Administrator Jim Bridenstine Monday called Kraft "a national treasure," saying "We stand on his shoulders as we reach deeper into the solar system, and he will always be with us on those journeys."Kraft became known as "the father of Mission Control" and in 2011 NASA returned the favor by naming the Houston building that houses the nerve center after Kraft."It's where the heart of the mission is," Kraft said in an April 2010 AP interview. "It's where decisions are made every day, small and large ... We realized that the people that had the moxie, that had the knowledge, were there and could make the decisions."That's what Chris Kraft's Mission Control was about: smart people with knowledge discussing options quickly and the flight director making a quick, informed decision, said former Smithsonian Institution space historian Roger Launius. It's the place that held its collective breath as Neil Armstrong was guiding the Eagle lunar lander on the moon while fuel was running out. And it's the place that improvised a last-minute rescue of Apollo 13 — a dramatic scenario that later made the unsung engineers heroes in a popular movie.Soon it became more than NASA's Mission Control. Hurricane forecasting centers, city crisis centers, even the Russian space center are all modeled after the Mission Control that Kraft created, Launius said.Leading up to the first launch to put an American, John Glenn, in orbit, a reporter asked Kraft about the odds of success and he replied: "If I thought about the odds at all, we'd never go to the pad.""It was a wonderful life. I can't think of anything that an aeronautical engineer would get more out of, than what we were asked to do in the space program, in the '60s," Kraft said on NASA's website marking the 50th anniversary of the agency in 2008.In the early days of Mercury at Florida's Cape Canaveral, before Mission Control moved to Houston in 1965, there were no computer displays, "all you had was grease pencils," Kraft recalled. The average age of the flight control team was 26; Kraft was 38."We didn't know a damn thing about putting a man into space," Kraft wrote in his autobiography. "We had no idea how much it should or would cost. And at best, we were engineers trained to do, not business experts trained to manage."NASA trailed the Soviet space program and suffered through many failed launches in the early days, before the manned flights began in 1961. Kraft later recalled thinking President John F. Kennedy "had lost his mind" when in May 1961 he set as a goal a manned trip to the moon "before this decade is out.""We had a total of 15 minutes of manned spaceflight experience, we hadn't flown Mercury in orbit yet, and here's a guy telling me we're going to fly to the moon. ... Doing it was one thing, but doing it in this decade was to me too risky," Kraft told AP in 1989."Frankly it scared the hell out of me," he said at a 2009 lecture at the Smithsonian.One of the most dramatic moments came during Scott Carpenter's May 1962 mission as the second American to orbit the earth. Carpenter landed 288 miles off target because of low fuel and other problems. He was eventually found safely floating in his life raft. Kraft blamed Carpenter for making poor decisions. Tom Wolfe's book "The Right Stuff" said Kraft angrily vowed that Carpenter "will never fly for me again!" But Carpenter said he did the best he could when the machinery malfunctioned.After the two-man Gemini flights, Kraft moved up NASA management to be in charge of manned spaceflight and was stunned by the Apollo 1 training fire that killed three astronauts.Gene Kranz, who later would become NASA's flight director for the Apollo mission that took man to the moon, said Kraft did not at first impress him as a leader. But Kranz eventually saw Kraft as similar to a judo instructor, allowing his student to grow in skills, then stepping aside."Chris Kraft had pioneered Mission Control and fought the battles in Mercury and Gemini, serving as the role model of the flight director. He proved the need for real-time leadership," Kranz wrote in his book, "Failure Is Not An Option: Mission Control from Mercury to Apollo 13 and Beyond."NASA eventually beat Kennedy's deadline, landing the first men on the moon in July 1969. Kranz watched from Mission Control as his underlings controlled Apollo 11, but then for the near-disaster in flight on Apollo 13, he stepped in for the key decisions. He later became head of NASA's Johnson Space Center.Born in 1924, Kraft grew up in Phoebus, Va., now part of Hampton, about 75 miles southeast of Richmond. In his autobiography, Kraft said with the name Christopher Columbus Kraft Jr., "some of my life's direction was settled from the start."After graduating from Virginia Polytechnic Institute in 1944, Kraft took a job with aircraft manufacturer Chance Vought to build warplanes, but he quickly realized it wasn't for him. He returned to Virginia where he accepted a job with the National Advisory Committee for Aeronautics, not far from Phoebus.Kraft's first job was to figure out what happens to airplanes as they approach the speed of sound.After his retirement, Kraft served as an aerospace consultant and was chairman of a panel in the mid-1990s looking for a cheaper way to manage the shuttle program. Kraft's panel recommended a contractor take over the day-to-day operations of the shuttle.Later, as the space shuttle program was being phased out after 30 years, Kraft blasted as foolish the decision to retire the shuttles, which he called "the safest machines ever built." He said President Barack Obama's plan to head toward an asteroid and Mars instead of the moon was "all hocus-pocus."Kraft said he considered himself fortunate to be part of the team that sent Americans to space and called it a sad day when the shuttles stopped flying."The people of Mercury, Gemini, and Apollo are blossoms on the moon. Their spirits will live there forever," he wrote. "I was part of that crowd, then part of the leadership that opened space travel to human beings. We threw a narrow flash of light across our nation's history. I was there at the best of times."Kraft and his wife, Betty Anne, were married in 1950. They had a son, Gordon, and a daughter, Kristi-Anne. 7877
