WASHINGTON — President Donald Trump says the Food and Drug Administration has issued an emergency use authorization for convalescent plasma to treat COVID-19 patients.WATCH PRESS CONFERENCE:Trump, announcing the decision Sunday at the White House, called convalescent plasma a “powerful therapy.” He says the FDA’s action will expand access to the treatment, which is already being used. The treatment involves transferring antibodies from recovered COVID-19 patients to patients suffering from the disease.On Sunday, Trump said the administration have provided million to fund the Mayo Clinic study that studied the efficiency in patients that have the virus."Through this study, over 100,000 Americans have already enrolled to receive this treatment, and it is proven to reduce mortality by 35%," Trump said. "It's a tremendous number. The FDA, M.I.T., Harvard, and Mount Sinai Hospital have also found convalescent plasma to be a very effective method of fighting this horrible disease. Based on the science and the data, the FDA has made the independent determination that the treatment is safe and very effective."Trump also announced the administration provided up to 0 million to the American Red Cross and America's blood centers to support the collection of up to 360,000 units of plasma.Department of Health and Human Services Secretary Alex Azar said that patients with the virus who were treated within three days of being diagnoses benefited the most from the treatment."We saw about a 35% under survival in the patients who benefited most from the treatment, who were patients under 80 and not on artificial respiration," Azar said.The announcement follows days of suggestions by White House officials of politically motivated delays by the FDA in approving a vaccine and treatments for the disease caused by the coronavirus.Trump made the announcement on the eve of the Republican National Convention that will nominate him to run against Democrat Joe Biden. 1988

Voters in Maine are trying out a new election system this year.“It is going to be used this fall for the first time in the presidential race, and that was a focus of a series of court challenges that went back and forth up though just a few weeks ago before it was finally determined, yes it will be used in the presidential race,” said Mark Brewer, Professor of Political Science at the University of Maine.What is ranked-choice voting? And how does it differ from how you fill out the more traditional “choose one,” or plurality, ballot design?“Normally you'll have a grid of candidates, all the candidate names on the left side and all of your choice columns along the top,” said Chris Hughes with the Ranked Choice Voting Resource Center. “Once we get everybody's ballots in, you count up all the first choices. If anyone has the majority, they get 50% of all those first choices, then that person is the winner.”However, if no candidate gets 50%, “you eliminate whoever has the fewest first choices and count the second choices on those ballots instead,” Hughes said.Ranked-choice voting has already been used for some local elections in states like California.“The big surge we’ve seen in the last 20 years started in San Francisco. San Francisco adopted ranked-choice voting in 2002 to eliminate their run off elections. Now they have a single general election,” Hughes said. “The last 20 years we’ve seen this huge growth, even between 2016 and 2020 we’ve seen five more cities adopt ranked-choice voting.”Why is Maine making the change now, in the brink of a critical presidential race? It’s a decision that was made four years ago. In 2016, the Ranked Choice Voting Act was passed by Maine voters, which meant ranked-choice voting would be used in certain statewide elections going forward.However, with every type of voting -- and there are many methods -- there are pros and cons.“In simpler elections ranked choice voting is probably going to do a decent job. But in more complicated elections where there are a bunch of candidates and it’s a tight race you run more of a risk of anomalies occurring,” said Aaron Hamlin with The Center for Election Science.What does this voting method mean for Maine, and the U.S. as a whole this election?“Ranked choice is going to come into play in the United States Senate race here in Maine,” Brewer said.“It’s not inconceivable that the Maine Senate race ends up deciding control of the U.S. Senate, and we're not going to know the outcome of the Maine Senate rate on election night. I can't imagine we will. It's going to be days after.” That is, if one of the Senate candidates doesn’t receive a 50% majority vote.“You don't have to start the reallocation process unless someone fails to get 50%,” he said.This Election Day, five more cities and two states, Alaska and Massachusetts, will vote on using ranked-choice voting in their future elections as well. 2920

Walmart is retreating from Europe, merging its UK supermarket business Asda with bigger rival Sainsbury's.In return, Walmart will receive ￡2.97 billion (.1 billion) in cash and a 42% stake in the combined business, the companies said in a statement on Monday.The deal values Asda at ￡7.3 billion ( billion), and creates a mega retailer with 2,800 stores and combined sales of roughly ￡51 billion ( billion).The sale of Asda follows Walmart's exit from Germany, its other major outpost in Europe, in 2006.Walmart could use the cash to fuel its expansion in other international markets. The US retailer is reportedly close to agreeing to invest in India's Flipkart, an online retailer that has also attracted attention from Amazon."This proposed merger represents a unique and bold opportunity, consistent with our strategy of looking for new ways to drive international growth," Judith McKenna, the CEO of Walmart International, said in a statement.The combination with Asda will give Sainsbury's more firepower as it confronts digital competitors including Amazon and aggressive discount chains, such as Germany's Lidl and Aldi.It also creates a new UK market leader: Sainsbury's and Asda together control over 31% of the grocery market, according to Kantar Worldpanel. The current industry front runner, Tesco, has nearly 28%.Regulators will have a close look at the deal, but the geographical distribution of Sainsbury and Asda stores could limit concerns over reduced competition.Upmarket Sainsbury's is strong in southern England, while Asda, which tends to have larger stores and lower prices, is well represented in the north. Together, the supermarket chains employ 330,000 people.The UK Competition and Markets Authority last year approved Tesco's takeover of wholesaler Booker, saying the deal would not reduce competition in the sector, which is known for its razor-thin margins and frequent price wars. 1929

Walmart is suing the U.S. government in a pre-emptive strike in the battle over its responsibility in the opioid abuse crisis.The government is expected to take civil action against the world’s largest retailer, seeking big financial penalties, for the role its pharmacies may have played in the crisis by filling opioid prescriptions.But on Thursday, Walmart filed a lawsuit saying that the Justice Department and the Drug Enforcement Administration are blaming the company for the government’s own lack of regulatory and enforcement policies to stem the crisis.Walmart says it is seeking a declaration from a federal judge that the government has no lawful basis for seeking civil damages from the company. It is also seeking to clarify its legal rights and duties under the Controlled Substance Act.Walmart operates more than 5,000 pharmacies in its stores around the country.“Walmart and its pharmacists find themselves in an untenable position,” the company based in Bentonville, Arkansas, says in the lawsuit filed in the U.S. District Court in the Eastern District of Texas. “Under defendants’ sweeping view, Walmart and its pharmacists may be held liable — perhaps even criminally — for failing to second-guess DEA-registered doctors and refuse their prescriptions. But if pharmacists do so, they may face the wrath of state medical boards, the medical community at large, individual doctors, and patients.”Walmart says in the suit that the Justice Department identified hundreds of doctors who have written problematic prescriptions that Walmart’s pharmacists allegedly should not have filled. But nearly 70% continue to have active registrations with the DEA, the lawsuit says.“In other words, defendants want to blame Walmart for continuing to fill purportedly bad prescriptions written by doctors that DEA and state regulators enabled to write those prescriptions in the first place and continue to stand by today,” the suit says.The lawsuit names the Justice Department and Attorney General William Barr as defendants. It also names the DEA and its acting administrator, Timothy Shea.In the suit, Walmart describes a government probe of the company that began in December 2016 and calls it a “misguided criminal investigation” conducted by the U.S. Attorney’s office for the Eastern District of Texas. Walmart says it fully cooperated with the probe.In the spring of 2018, the office advised that it intended to indict the company. In August 2018, Walmart said that officials at the Department of Justice recognized that there was no plausible basis for a criminal indictment, and the department formally declined to prosecute Walmart. But the civil investigation continued.The initial investigation was a subject of a story in ProPublica published in March. ProPublica reported that Joe Brown, then U.S. attorney for the Eastern District of Texas office, spent years pursuing a criminal case against Walmart for its opioid prescription practices, only to have it stymied after the retail giant’s lawyers appealed to senior officials in the Justice Department.Two months later, Brown resigned. He didn’t give a reason for his departure except to say he would be “pursuing opportunities in the private and public sectors” and “some of those will become apparent in the coming days. Brown went into private practice in the Dallas areaA spokeswoman for the U.S. attorney’s office in Texas that handled the investigation referred questions to the Justice Department in Washington. The Justice Department declined to comment. 3541
