Moderator Kristen Welker, with the help of an offstage mute button, helped give Americans a substantive head-to-head debate over leadership that had been missing during the presidential campaign. The NBC News White House correspondent, in her first time moderating a general election debate, kept tight control of the discussion between President Donald Trump and Democrat Joe Biden. Trump, possibly deterred by the mute button, resisted the interruptions that led to criticism of his performance in the first debate. Welker guided the candidates through discussions about the coronavirus, climate change, health care and race in America.While Thursday marked Welker's first time moderating a debate between two nominees, she was among a panel of NBC News moderators who led a Democratic debate last year. Welker earned praise from her colleagues both at NBC News and the White House Press Corps. 905

Monday morning, the CDC removed what it calls was a “draft version of proposed changes” to their website that seemed to indicate they were embracing mounting evidence that COVID-19 is airborne and is transmitted through tiny droplets that can linger in the air and spread farther than six feet.“A draft version of proposed changes to these recommendations was posted in error to the agency’s official website. CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the update language will be posted,” the CDC website now reads.The website was changed over the weekend, according to multiple media reports, to reflect several updates to their guidance about how COVID-19 spreads and preventative measures to take.The “draft” changes included stating COVID-19 transmits through the air and warned about poorly ventilated situations, saying that is “thought to be the main way the virus spreads.”On the Centers for Disease Control and Prevention’s website about coronavirus, under how it spreads, they listed the main way as: “Through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection.”They also had updated the guidance that particles can remain in the air longer and travel farther than originally thought.“There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes). In general, indoor environments without good ventilation increase this risk,” the CDC website read over the weekend.The website has been changed back to their previous guidance which states COVID-19 is believed to be transferred through larger droplets through close contact, closer than six feet, with a person who coughs, sings, or otherwise expels these larger droplets carrying the virus.The updated draft passages and comments on smaller particles and ventilation appeared to embrace recent studies from the CDC.Including one released by the CDC earlier this month showing Americans with positive COVID-19 test results were twice as likely to eat at a restaurant or cafe than those who tested negative.“Reports of exposures in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance. Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use,” that report stated.In the “draft” changes to the CDC website, they included a preventative measure about ventilation, stating “Airborne viruses, including COVID-19, are among the most contagious and easily spread.” That passage is no longer on the website.The draft changes on the air transmission of COVID-19 also came on the heels of the CDC’s director, Dr. Robert Redfield, saying masks could be even more helpful in combating the coronavirus than a vaccine. President Donald Trump said later Redfield was confused by the question and misspoke.The World Health Organization changed their guidance and noted the prevalence of air transmission, and those particles lingering in the air, earlier this summer in July. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 3665

MIRAMAR, Calif. (KGTV) - Marine Corps Air Station Miramar unleashed the potential of their renewable energy powered grid Tuesday to support San Diego during a heat wave."We've reached a point where we really need to take action to conserve," Jessica Packard, Communications Manager at SDG&E, said. The California Independent System Operator issued a Flex Alert spanning Sunday through Wednesday, which forced SDG&E to begin hour long rotating black outs across the county.Mick Wasco, Installation Energy Manager at MCAS Miramar, said they have a great relationship with SDG&E and heard over the weekend the power grid was at maximum capacity.Wasco said they took action, "although not entirely ready we did whatever we could to get our system online and help support as soon as possible."Wasco said the base has been working on a microgrid for more than a decade. It is powered by three sources: solar, landfill gas in partnership with Fortistar, and a power plant that uses natural gas and diesel, created in partnership with Schneider Electric and Black and Veatch.Wasco said the power plant works smarter, "these are not backup generators, these are generators with the best equipment possible to clean the emissions."The system succeeded Tuesday, eliminating six megawatts of usage from San Diego's grid. That saved about 2,000 homes from going dark."I don't know that everybody knows what we're capable of doing at Miramar and I think the goal is over the next couple years is to demonstrate that," Wasco said.The system has won multiple awards, including the 2019 Secretary of Defense Environmental Award for Sustainability and the Environmental Protection Agency's National Award for Energy in 2015."I think this is only the beginning and we can greatly improve our abilities in the coming years," Wasco said he wants to continue working with businesses and the community to utilize the system the most efficient and beneficial way possible.The system was initially needed to power the base during a disaster. The Navy calls for bases to be able to power themselves for two weeks. MCAS Miramar can power themselves without extra supplies for three weeks.Wasco said if they did get supplies, like diesel, they could potentially power themselves indefinitely. 2280

MILWAUKEE — Surveillance video captured two porch pirates on a casual morning stroll. But what they don't know is that the owner of the package they're about to steal actually wants it to get taken. "Usually I get very mad when I see the package get stolen, but now this one I was like proud to show the video," said Jamie, who left a package of sweet revenge on her Milwaukee porch.Out of fear of retaliation, Jamie asked that her identity be concealed and to only use her first name. She says they've had about eight packages stolen from their front porch and have tried everything to fight back. They installed security cameras, asked for signed deliveries and even had items placed behind a fence. But somehow the thieves continued to be successful. Eventually, they decided to have everything delivered to work, but after a gift sent to her a month ago was stolen as well, she decided that was enough. "That's when we ordered the next package," she said. "We went on to a website that does anonymous deliveries and you can pick from all sorts of different fecal matter. The cheapest one is cow, we decided to go in full blast and we chose gorilla." The thieves didn't like what they had scooped up, and ended up tossing the item into a neighbor's yard. But they aren't the only thieves she's caught on camera. Video also shows a woman stealing that gift someone sent Jamie, that contained memorial stickers honoring her late father. "She threw it because it wasn't anything important to her but to me that was the most important package that had been taken off our porch," said Jamie. A neighbor ended up finding the discarded stickers in a nearby park. Jamie says she's tried to report the thefts to police, but she's been told it's a lost cause and the chances of catching these criminals are slim. So she hopes a little package payback will prevent thefts in the future. "We do live in a nice neighborhood," she said. "It's a nice a street, they're nice neighbors, we just don't know why it keeps happening to us."  2106

Nearly 100 migrants will be deported following an incident Sunday in which hundreds of people rushed the US-Mexico border, Mexican authorities say.About 500 migrants on the Mexican side of the border overwhelmed police blockades near the San Ysidro Port of Entry on Sunday, two journalists in Tijuana told CNN. US Customs and Border Protection, which said that as many as 1,000 people tried to enter the US illegally, said the migrants threw projectiles that struck several US Border Patrol agents.Agents fired tear gas at the group. Video of the scene showed a cloud of tear gas that sent people running and screaming, including families with young children.The incident forced a temporary closure of the major border crossing into San Diego. 751
