ATLANTA - In a memo this week, Delta Airlines’ CEO told staff nearly 700 passengers have been placed on the no-fly list in 2020 for refusing to comply with policies requiring masks on planes.This is a sharp increase from the 460 banned passengers the airline reported in October. Delta and other airlines have been adding mask rule-breaking passengers to the no-fly list since early in the pandemic.Delta is not alone, latest numbers from United report about 430 passengers of that airline have been added to the no-fly list for not following their mask policy, and 88 have been banned from JetBlue flights.A Department of Defense study found that masks, combined with airplanes’ air filtration systems, can greatly reduce the risk of transmitting the coronavirus during a flight.While that sounds like a lot of passengers, Delta told Fox News they are flying about 1 million customers per week.In the message to staff Wednesday, Delta’s CEO Ed Bastian thanked employees for taking unpaid leave and manage reductions in hours earlier this year, which helped them be one of the few airlines that avoided involuntary furloughs. Ground workers and headquarters employees were cut to three or four days a week.However, he is now asking employees again to take unpaid leaves of absence to help the company save money, according to the staff memo. Bastian said Wednesday that Delta will need more employees to take unpaid leave “for the foreseeable future.”“I ask everyone to consider whether a voluntary leave makes sense for you and your family,” he said in a memo to employees.About 15,000 Delta employees have already left the airline through buyouts and early retirements, according to the Atlanta Journal Constitution.It's a sign of the deepening slump in air travel with coronavirus cases rising across the country. Delta expects to lose up to million a day on average during the fourth quarter.Delta is also one of the last airlines to block the middle seats on their planes, and says they will do so through March 2021.Unlike American and United, Atlanta-based Delta has avoided furloughs since the pandemic started by convincing thousands of workers to retire early or take unpaid leave.But the air travel recovery seems to be faltering. Passenger traffic rose over Thanksgiving week but has dropped since then. 2327

As questions arise over when a coronavirus vaccine should be granted FDA approval, the leaders of several major pharmaceutical companies announced they have signed a pledge not to rush the development of a vaccine.The companies, AstraZeneca, BioNTech, GlaxoSmithKline, Johnson, Merck, Moderna, Novavax, Pfizer and Sanofi, released a joint statement on Tuesday confirming the pledge.The pledge includes the following points:Always make the safety and well-being of vaccinated individuals our top priority.Continue to adhere to high scientific and ethical standards regarding the conduct of clinical trials and the rigor of manufacturing processes.Only submit for approval or emergency use authorization after demonstrating safety and efficacy through a Phase 3 clinical study that is designed and conducted to meet requirements of expert regulatory authorities such as FDA.Work to ensure a sufficient supply and range of vaccine options, including those suitable for global access.There has been pressure on both the FDA and manufactures to develop and approve a vaccine for the coronavirus. There have been more than 190,000 coronavirus-related deaths in the US since March, and the economic impact of the virus has cost millions of jobs.While most developed countries have not had the same public health pain as the US, the economic impact of the virus has been felt worldwide. The International Monetary Fund estimates a nearly 5% loss in global GDP in 2020.In Russia, the country claimed to begin distributing a coronavirus vaccine despite US-based vaccine candidates likely being months away from being able to demonstrate efficacy.The pressure domestically has also ratcheted up as President Donald Trump has suggested a vaccine could be ready by this fall’s presidential election."We're going to have a vaccine very soon... maybe even before a very special date, you know what date I'm talking about,” Trump said on Monday.In late August, the CDC told states to begin to prepare distributing a vaccine by Nov. 1. But Surgeon General Jerome Adams said that just because states will be ready to help distribute a vaccine on Nov. 1 does not mean a vaccine will be ready by then."We've always said that we're hopeful for a vaccine by the end of this year or the beginning of next year,” Adams told Good Morning America."We want to make sure states are available to distribute it," he added.The companies signing on the pledge said that the FDA has strict protocols for vaccine candidates. A typical vaccine trial takes one to three years, but the companies believe only a safe and effective vaccine will be granted approval.“FDA has established clear guidance for the development of COVID-19 vaccines and clear criteria for their potential authorization or approval in the US,” the companies wrote in the pledge. “FDA’s guidance and criteria are based on the scientific and medical principles necessary to clearly demonstrate the safety and efficacy of potential COVID-19 vaccines. More specifically, the agency requires that scientific evidence for regulatory approval must come from large, high quality clinical trials that are randomized and observer-blinded, with an expectation of appropriately designed studies with significant numbers of participants across diverse populations.” 3296

As the counting of ballots continue, one trend is emerging: the final result will be close. A potential consequence of that will be a recount. Perhaps in one state or in multiple states. RECOUNT RULESEach state handles recounts differently. For example, in Arizona, an automatic recount is triggered if the margin between candidates is less than or equal to 0.1 percent of the votes cast. In Georgia, candidates can request recounts if the margin is no more than .5 percent of total votes cast.DO RECOUNTS CHANGE ANYTHINGAccording to FairVote.org, recounts rarely change races. Since 1980, there have been 5,778 statewide elections.There have only been 31 completed statewide recounts.Only three have been overturned because of a recount.Perhaps the most famous recount of all was in Florida in 2000.But the 2000 Florida Recount only shifted the final margins by 1,247 votes or 0.02%In a recount in Wisconsin in the 2016 Presidential race, the final margin only changed by 571 votes. "I believe recounts in themselves are not in favor of those who have lost a race unless it's a very close margin," Dr. Eric Claville, a political scientist with Norfolk State University said. 1183

As parents are deciding whether to purchase Halloween costumes for their children amid the coronavirus pandemic, one Ohio man is ready to safely welcome trick or treaters to his home.Andrew Beattie has installed a 6-foot chute for candy so he can remain distanced from trick or treaters on Beggars’ Night.Beattie says that the chute will be “touch-free” as children will have the treats drop into their candy bucket without having to come in contact with Beattie. For added safety, Beattie says that he will wear a mask and continually change gloves in order to keep children safe.“I want our youngins to be able to have some sense of normalcy and maybe a little bit of exercise in all this madness, and I've put a LOT of thought into how to do so safely, and I appreciate your concern,” Beattie said in a viral Facebook post published earlier this week.Beattie said the chute is a six-foot long tube of cardboard that is four inches in diameter. He said he was able to install the chute on his porch in 20 minutes.“If this candy chute makes things easier or safer, AND gives those with mobility challenges more of a chance to participate, then what's the harm? An ounce of prevention is worth a pound of cure, ya' know,” Beattie wrote.Beattie has created a Facebook group where he hopes to share ideas with others this fall ahead of Halloween. The group has nearly 10,000 members as of late Thursday. 1409

Attorneys for former FBI Director James Comey and the US House of Representatives fought in court Friday afternoon over whether Comey must testify to Congress in a private hearing next week.While Comey technically seeks to pause or kill the subpoena, he is using the case to air his accusation that members of the Republican-led House and Senate selectively leak details for their own benefit when they call witnesses to testify in private.Attorneys for the House called Comey's request "so extraordinary and frivolous that, as far as undersigned counsel is aware, no district court in the history of the Republic has ever granted such a request."Judge Trevor McFadden said at the hearing that he hoped to rule Monday morning after meeting again with both legal teams.The meat of Friday's dispute was how each side characterizes Comey's congressional subpoena. Comey's team says Congress is in violation of its own rules by not conducting its fact-finding hearing in public. The hearing won't require that level of secrecy because no sensitive law enforcement information is expected to be discussed, Comey's team said.The House general counsel countered that because Comey's testimony would be a deposition with staff, a public session isn't required.McFadden asked whether Comey could release a transcript of his testimony to get the full picture before the public. But Comey's lawyers said that would take too much time, allowing leaks of the information before Comey could release his full testimony.When McFadden asked Comey's attorney whether he agreed with the House that a judge has never limited Congress in this way before, the lawyer David Kelley responded, "Here's your opportunity, Judge."Comey has said he would like to testify publicly about the separate investigations into Hillary Clinton's email practices and Russian interference in the 2016 election -- in front of live TV cameras as he has done before."The broader purpose of these tweets and leaks appears to be to mislead the public and to undermine public confidence in the FBI and the DOJ during a time when President Trump and members of his administration and campaign team are reported to be under investigation by Special Counsel Robert Mueller and other law enforcement authorities," Comey wrote in his complaint. He says he is a "victim" of Congress' "unauthorized and abusive tactics."Comey did not attend Friday's hearing in person.He has asked the judge to issue an emergency order to pause the congressional proceedings and to quash the subpoena. In theory, Comey could lose his court challenge and still win what he's seeking, if he manages to convince the judge to pause his subpoena until the House flips to Democratic control at year's end.The case initially was set to be heard by Judge Timothy Kelly, a Trump appointee, then was reassigned randomly to McFadden, also a Trump appointee, after Kelly likely recused from the case. 2941
