The coronavirus pandemic may have started earlier than previously thought, according to scientists from the CDC.A study from government scientists published November 30 appears to confirm what some health experts have suggested, patients infected with COVID-19 were in the US before the beginning of 2020.“The findings of this report suggest that SARS-CoV-2 infections may have been present in the U.S. in December 2019, earlier than previously recognized. These findings also highlight the value of blood donations as a source for conducting SARS-CoV-2 surveillance studies,” the report states.The first officially documented case of COVID-19 in the US was reported on January 19, a person who had returned to the US after traveling from China.The World Health Organization was alerted to the novel coronavirus by officials in Wuhan, China on December 31, 2019. The CDC researchers say further reports have identified a patient in Wuhan with COVID-19 symptoms as early as December 1, 2019.The study looked at more than 7,000 routine blood donation samples taken by the American Red Cross from people in nine states between December 13, 2019 and January 17, 2020.They found COVID-19 antibodies in 106 samples, mostly from the states of California, Oregon and Washington, from blood collected between December 13-16, 2019. Other samples that indicated COVID-19 antibodies were from Connecticut, Iowa, Massachusetts, Michigan, Rhode Island, and Wisconsin taken in early January 2020.“The presence of these serum antibodies indicate that isolated SARS-CoV-2 infections may have occurred in the western portion of the United States earlier than previously recognized or that a small portion of the population may have pre-existing antibodies that bind SARS-CoV-2,” the report states.Scientists acknowledge that patients presenting with what is now known as COVID-19 symptoms before mid-January would likely not have had clinical samples taken or kept because of how new the virus was. Therefore, the CDC used the existing repository collected by the American Red Cross during their routine blood donation process.“These specimens were previously archived for potential future studies to identify emerging transfusion-transmissible infections but were re-purposed for the present study,” researchers stated.Researchers caution that these results are subject to limitations. Although they detected antibodies, that does not mean they are “true positive” COVID-19 tests. In order to get a true positive, a different test would need to be a run. 2545

The election may be over but the term of President Donald Trump is not. So what can President Trump do between now and January 20, 2021?FIVE BIG AREASPresident Trump will likely be exploring options without Congress. The most obvious actions include the power to pardon, appoint top officials, fire top officials, approve military action and issue executive orders. President Trump could very well pardon anyone he wants, including former advisers Michael Flynn or Paul Manafort. President Trump may also explore the possibility of preemptively pardoning members of his own family as various investigations continue. HIRING AND FIRING President Trump has already begun the process of firing some top officials, including Secretary of Defense Mark Esper. President Trump may exercise that authority with other officials, such as the FBI Director who he has publicly criticized. The commander-in-chief may also continue to appoint top posts. He appears poised to confirm Judy Sheldon to the Federal Reserve before the end of his term, a position which has the power to influence interest rates and monetary policy for decades to come. EXECUTIVE ACTIONSPresident Trump will also continue to have authority to conduct military strikes since he is Commander-in-Chief. He will also have the ability to issue executive orders, although any order he issues could be immediately reversed when President-elect Biden takes office. 1428

The FDA has given the final go-ahead to Pfizer-BioNTech's coronavirus vaccine.Shots will begin in a few days after the decision, but initial doses will be scare and rationed to health workers and nursing home residents and staff first. Enough vaccinations for the general population isn't expected until spring, prompting experts to urge the public to continue using face coverings and physically distance through the winter.Authorization had been expected Saturday morning, after an advisory panel recommended approval of the vaccine Thursday evening. According to reports, the agency was working to move it up to Friday evening.Friday morning, President Donald Trump lashed out at the Food and Drug Administration and its commissioner, Dr. Stephen Hahn, for not moving faster. Trump tweeted the FDA “is still a big, old, slow turtle. Get the dam vaccines out NOW, Dr. Hahn @SteveFDA. Stop playing games and start saving lives!!!” 939

The Department of Justice said Monday that an NYPD officer had been arrested and charged with allegedly acting as an "illegal agent" for the Chinese government.In a statement released Monday, the DOJ said that in addition to illegal agent charges, 33-year-old Baimadajie Angwang has also been charged with committing wire fraud, making false statements and obstructing an official proceeding.The DOJ alleges that Angwang was providing information about Chinese citizens in the New York area to the government of the People's Republic of China. He was also allegedly "developing intelligence sources within the Tibetan community."According to Scripps station WPIX in New York, Angwang is a Tibetan native and resident of Long Island. He worked in the NYPD's 111th precinct in Queens and was also employed by the U.S. Army Reserve as a staff sergeant.Angwang initially arrived in the U.S. on a cultural exchange visa. Once that visa was renewed, he overstayed the length and later claimed asylum "on the basis that he had allegedly been arrested and tortured" in China due to his Tibetan heritage.A complaint alleges that Angwang has worked under the control of the Chinese government since 2014. He allegedly told his Chinese government handler that he wanted to be promoted within the NYPD "so that he could assist the PRC and bring 'glory to China.'""As alleged in this federal complaint, Baimadajie Angwang violated every oath he took in this country. One to the United States, another to the U.S. Army, and a third to this Police Department," NYPD Commissioner Dermot Shea said. "From the earliest stages of this investigation, the NYPD's Intelligence and Internal Affairs bureaus worked closely with the FBI's Counterintelligence Division to make sure this individual would be brought to justice.""The defendant allegedly violated the trust of his community and the New York City Police Department on behalf of a foreign power, the People's Republic of China. This type of conduct simply cannot be tolerated," said Alan E. Kohler, Jr., Assistant Director of the FBI's Counterintelligence Division. "This case serves as yet another reminder that China represents the biggest counterintelligence threat to the United States and that the FBI and our partners will be aggressive in investigating and stopping such activities within our nation."If convicted, Angwang faces a maximum of 55 years in prison. 2412

The COVID-19 pandemic has been a difficult and stressful time for families, but we're seeing one silver lining when it comes to fathers and their kids.Nearly 70% of dads in a recent study from the Harvard Graduate School of Education say they're feeling closer to their kids right now.The dads have had to be home more than usual, but one of the people involved with the study also believes it's helping that dads may be less distracted with work than they usually are.Also, parents' social lives have changed, so they're doing things with their kids they may have done with their friends previously.Dads in the study say they're also getting to know their kids better. More than half say they're spending more time talking to their children about things that are important to them.“I think we're all better parents when we know our kids better,” said Richard Weissbourd, who directs the Making Caring Common Project at Harvard. “I mean it's respectful to enable our kids to really speak, but we also learn a lot about them and it deepens our relationships with them and it also helps us I think in being mentors and guides to them when they make key decisions in their lives.”The Making Caring Common Project is a national effort to make moral and social development priorities in raising kids.Weissbourd is worried there will be a strong pull to return to our normal lives and dads' relationships won't continue in the same way.But you can take steps now to keep those bonds.“I really encourage fathers to establish rituals and routines with their kids now, like if you're going for a walk every weekend with your kid, continue doing that even when the pandemic is over,” said Weissbourd. “If you're playing games with your kid, develop a ritual around playing games with your kids or activities.”He says more fathers are also watching TV with their kids and talking with them about what's going on in the world surrounding the pandemic and the protests. He's hopeful that ritual will continue too. 2008
