The White House declined to comment Friday about a purported remark about Sen. John McCain by a communications staffer."I'm not going to comment on an internal staff meeting," press secretary Sarah Sanders said of Kelly Sadler's remark that McCain, who is being treated for brain cancer, is "dying."Sanders confirmed Sadler still works at the White House.On Thursday, Sadler, a special assistant who handles surrogate communications, told other staffers that McCain's opposition to President Donald Trump's CIA director nominee, Gina Haspel, does not matter because "he's dying anyway," a White House official told CNN. 627

The smoke from dozens of wildfires in the western United States is stretching clear across the country — and even pushing into Mexico, Canada and Europe. While the dangerous plumes are forcing people inside along the West Coast, residents thousands of miles away in the East are seeing unusually hazy skies and remarkable sunsets.The wildfires racing across tinder-dry landscape in California, Idaho, Oregon and Washington are extraordinary, but the long reach of their smoke isn’t unprecedented. While there are only small pockets in the southeastern U.S. that are haze free, experts say the smoke poses less of a health concern for those who are farther away.The sun was transformed into a perfect orange orb as it set over New York City on Tuesday. Photographs of it sinking behind the skyline and glinting through tree leaves flooded social media. On Wednesday, New Jersey residents described a yellow tinge to the overcast skies, and weather forecasters were kept busy explaining the phenomenon and making predictions as to how long the conditions would last.On the opposite coast, air quality conditions were among some of the worst ever recorded. Smoke cloaked the Golden Gate Bridge and left Portland and Seattle in an ashy fog, as crews have exhausted themselves trying to keep the flames from consuming more homes and even wider swaths of forest.Satellite images showed that smoke from the wildfires has traveled almost 5,000 miles (8,000 kilometers) to Britain and other parts of northern Europe, scientists said Wednesday.The current weather system, which favors a westerly wind across the higher levels of the atmosphere, is to blame for the reach of the smoke, experts explained.“We always seem, at times, to get the right combination of enough smoke and the upper level jet stream to line up to bring that across the country, so we’re just seeing this again,” said Matt Solum with the National Weather Service’s regional operations center in Salt Lake City, Utah. “It’s definitely not the first time this has happened.”There could be some easing of the haze this weekend as a storm system is expected to move into the Pacific Northwest and could affect the conditions that helped the smoke travel across the country. But Solum said there’s always a chance for more smoke and haze to shift around.“Just due to all the wildfires that are going on, this is likely going to continue for a while,” he said. “You might have ebbs and flows of that smoke just depending on how the upper level winds set up.”Kim Knowlton, a senior scientist with the Natural Resources Defense Council in New York City, said she woke up Wednesday to a red sunrise and more haze.She said millions of people who live beyond the flames can end up dealing with diminished air quality as it’s not uncommon for wildfire smoke to travel hundreds of miles.Although the health impacts are reduced the farther and higher into the atmosphere the smoke travels, Knowlton and her colleagues said the resulting haze can exacerbate existing problems like asthma and add to ozone pollution. 3070

The U.S. will pay drug company Pfizer .95 billion to produce and deliver 100 million doses of the company's COVID-19 vaccine candidate should the drug prove effective in human trials the company said in a press release on Wednesday.Pfizer will deliver the vaccine if and when the drug receives Emergency Use Authorization from the FDA after a large-scale Phase 3 trial.According to the reports, the deal includes an option for the government to purchase an additional 500 million doses of the vaccine.“Expanding Operation Warp Speed’s diverse portfolio by adding a vaccine from Pfizer and BioNTech increases the odds that we will have a safe, effective vaccine as soon as the end of this year,” Health and Human Services Sec. Alex Azar said in a statement. “Depending on success in clinical trials, today’s agreement will enable the delivery of approximately 100 million doses of this vaccine to the American people.”Pfizer and German firm BioNTech are working together to develop the vaccine.On Monday, Pfizer said in a press release that results from Phases 1 and 2 of a German trial indicated that the drug "could potentially be administered safely, with a manageable tolerability profile," according to data from the tests.Biotech company Moderna is also working to develop a coronavirus vaccine. That candidate will move into Phase 3 testing by the end of the month, and the government has also agreed to purchase and distribute the drug should the large-scale test prove effective. 1497

The Trump administration has formally asked the Federal Communications Commission (FCC) to develop regulations that could apply to Facebook, Twitter and other such platforms.It's a key step toward President Donald Trump fulfilling his executive order to regulate social media.The order asks the FCC to clarify a section of law that has shielded tech companies from much litigation over internet content since 1996.The FCC — which is reviewing the Administration's petition — now has to decide whether to agree with the president's call for oversight or not.Legal experts say the agency has traditionally avoided regulating internet companies in the past. 662
