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 — A House Republican aide says Rep. Louie Gohmert has tested positive for the coronavirus.The 66-year-old Texas Republican was screened for the virus at the White House on Wednesday morning.Gohmert had gone to the White House because he was planning to fly to Texas with President Donald Trump aboard Air Force One. Gohmert had to cancel his trip and is planning to isolate.The aide wasn't authorized to publicly discuss Gohmert’s test result and spoke on condition of anonymity.Gohmert is one of the House’s most conservative and outspoken members.Gohmert is often seen without wearing a mask on Capitol Hill.On Monday, President Donald Trump's national security adviser, Robert O'Brien, tested positive for COVID-19, the highest-ranking member of the Trump administration to contract the virus. 815

WASHINGTON — U.S. health officials have started two new studies to test various blood thinners to try to prevent strokes, heart attacks, blood clots and other complications in COVID-19 patients.Doctors increasingly are finding blood clots throughout the bodies of many people who died from COVID-19 along with signs of damage they do to kidneys, lungs, blood vessels, the heart and other organs.National Heart, Lung and Blood Institute Director Gary Gibbons says that hospitals have been giving seriously ill patients anti-clotting drugs to try to prevent this, but “quite frankly, we didn’t know how best to treat it” in terms of which drugs or doses to use and at what stage of illness.The National Institutes of Health will coordinate a study in hospitalized patients comparing low and regular doses of the blood thinner heparin. The study will involve more than 100 sites around the world participating in a research effort with various governments, drug companies, universities and others to speed coronavirus therapies.A second study in COVID-19 patients not sick enough to need hospitalization will test various strategies against placebo pills: baby aspirin or low or regular doses of the anti-clotting drug apixaban, sold as Eliquis in the United States. The goal there is preventing blood clots or hospitalization.A third study starting later will test blood thinners for people who have recovered and no longer test positive for the coronavirus. Evidence is building that they may remain at higher risk for blood clots. 1538

WASHINGTON (AP) — Democrats ignored a veto threat and rammed legislation through the House Tuesday that would stymie President Donald Trump's bid for billions of extra dollars for his border wall, escalating a clash over whether he was abusing his powers to advance his paramount campaign pledge.The House's 245-182 vote to block Trump's national emergency declaration throws the political hot potato to the Republican-run Senate, where there were already enough GOP defections to edge it to the cusp of passage. Vice President Mike Pence used a lunch with Republican senators at the Capitol to try keeping them aboard, citing a dangerous crisis at the border, but there were no signs he'd succeeded."I personally couldn't handicap the outcome at this point," said Senate Majority Leader Mitch McConnell, R-Ky., who's planning a vote within the next three weeks.Senate passage would force Trump's first veto, which Congress would surely lack the votes to override. But the showdown was forcing Republicans to cast uncomfortable votes pitting their support for a president wildly popular with GOP voters against fears that his expansive use of emergency powers would invite future Democratic presidents to do likewise for their own pet policies.Underscoring their desire to avoid a tally suggesting that Trump's hold on lawmakers was weakening, House Republican leaders worked to keep the number of GOP supporters below 53. That's how many would be needed to reach a two-thirds majority of 288 votes, assuming all Democrats vote "yes," the margin required for a veto override.Thirteen House Republicans joined all voting Democrats Tuesday to support the Democratic resolution.The White House wrote to lawmakers formally threatening to veto the legislation. The letter said blocking the emergency declaration would "undermine the administration's ability to respond effectively to the ongoing crisis at the Southern Border."Republicans said Democrats were driven by politics and a desire to oppose Trump at every turn, and said Trump had clear authority to declare an emergency to protect the country. They also defended the president's claims of a security crisis along the boundary with Mexico, which he has said is ravaged by drug smugglers, human traffickers and immigrants trying to sneak into the U.S. illegally."We are at war on the Southern border with the drug cartels," said Rep. Pete Olson, R-Texas.Trump has asserted that barriers would stop drugs from Mexico from entering the U.S. In fact, government figures show that 90 percent of drugs intercepted from Mexico are caught at ports of entry, not remote areas where barriers would be constructed.Democrats said Republicans repeatedly accused former President Barack Obama of flouting the Constitution, which gives Congress control over spending, but are ignoring Trump's effort to do the same."Is your oath of office to Donald Trump, or is your oath of office to the Constitution?" House Speaker Nancy Pelosi, D-Calif., asked Republicans.They said Trump's push for the wall reflected a continuation of the anti-immigrant views that helped fuel his election."Since when do we call human beings in need a national emergency?" said Mexican-born Rep. Jesus "Chuy" Garcia, D-Ill. "Is he running out of insults for people like me?"Democrats also said the crisis is a fiction manufactured by Trump to dance around Congress' vote this month to provide less than .4 billion for barrier construction. That was well below the .7 billion Trump demanded as he futilely forced a record-setting 35-day federal shutdown."The president does not get to override Congress in a raucous temper tantrum over his inability to broker a deal" with lawmakers for more money, said Rep. Hank Johnson, D-Ga. Rep. Joaquin Castro, D-Texas, sponsor of the one-sentence measure blocking the declaration, called Trump's move "constitutional vandalism."Trump used a 1976 law to declare a national emergency and ordered the shift of .6 billion from military construction projects to wall building. Citing other powers, he intends to shift another .1 billion from Defense Department anti-drug efforts and a fund that collects seized assets.The money would be used to build steel barriers up to 30 feet tall and other barriers and for "law enforcement efforts," said a White House statement.In the Senate, three Republicans have said they will back Democrats' drive to block the emergency declaration: Maine's Susan Collins, Alaska's Lisa Murkowski and North Carolina's Thom Tillis. One more GOP defection would provide enough votes to approve the Democratic measure, assuming all Democrats and their independent allies back it.Republicans said senators asked Pence numerous questions about which projects Trump would divert to pay for the wall, with Sen. Richard Shelby, R-Ala., saying the discussion was "hearty." Shelby, who chairs the Senate Appropriations Committee, which controls spending, said his panel would quickly "backfill" money for military construction with other funds he did not identify."That issue won't stay alive long," Shelby told reporters.Sen. John Thune of South Dakota, the chief GOP vote counter, said there may be GOP attempts to amend the House measure, saying Republicans "think they have amendments that would improve it."That suggests that McConnell may try finding a way to add language that could sink the Democratic resolution or, perhaps, make it more palatable for Republicans. The law requires the Senate to vote on a measure within 18 days of receiving it from the House.Though presidents have declared 58 emergencies under the law, this is the first aimed at acquiring money for an item Congress has explicitly refused to finance, according to Elizabeth Goitein, co-director for national security at New York University Law School's Brennan Center for Justice. This is also the first time Congress has cast votes on whether to annul an emergency declaration, she said.Even with Democrats' effort near-certain to ultimately fail, several lawsuits have been filed aimed at blocking the money, including by Democratic state attorneys general, progressive and environmental groups. Those suits at the very least are likely to delay access to those funds for months or years.___AP Congressional Correspondent Lisa Mascaro and reporter Colleen Long contributed. 6336
