WASHINGTON, D.C. – The United States has reached another grim milestone in the COVID-19 pandemic, surpassing 9 million coronavirus cases.That’s according to a tally by Johns Hopkins University, which also shows the U.S. is closing in on 230,000 deaths from COVID-19.America continues to lead the world in the total number of cases and deaths, with India and Brazil quickly catching up.The milestone comes as around most states across the U.S. report increases in infections. Data shows the seven-day rolling average for daily new coronavirus cases in the U.S. rose over the past two weeks from 52,350 to more than 74,180.This marks a return to infection levels not seen since the summer surge.This recent surge comes on the heels of the 2020 presidential election, where the pandemic is top of mind for most voters. However, the candidates are framing the COVID-19 crisis in different ways. President Donald Trump is claiming the U.S. rounding the curve and is promising to return to country to normal with a forthcoming vaccine.Meanwhile, former Vice President Joe Biden is zeroing in on how the Trump administration has handled the pandemic, claiming it was mismanaged and far too many people have died or gotten sick. 1228

WASHINGTON (AP) -- U.S. Navy leaders are recommending a sweeping list of changes in sailor training, crew requirements and safety procedures to address systemic problems across the Pacific fleet that led to two deadly ship collisions earlier this year that killed 17 sailors, according to a copy of the report obtained by The Associated Press.A critical report scheduled to be released Thursday calls for about 60 recommended improvements that range from improved training on seamanship, navigation and the use of ship equipment to more basic changes to increase sleep and stress management for sailors.Another Navy report released Wednesday concluded that three collisions and a ship grounding this year were all avoidable, and resulted from widespread failures by the crews and commanders who didn't quickly recognize and respond to unfolding emergencies. Navy leaders publicly acknowledged those failings in a congressional hearing last month.RELATED: San Diego sailors killed in ship collisionThe USS John S. McCain and an oil tanker collided near Singapore in August, leaving 10 U.S. sailors dead. And seven sailors died in June when the USS Fitzgerald and a container ship collided off Japan. The USS Lake Champlain collided with a Korean fishing vessel in May and the USS Antietam struck bottom near a shoal in Tokyo Bay.As a result of the two deadly accidents, eight top Navy officers, including the 7th Fleet commander, were fired from their jobs, and a number of other sailors received reprimands or other punishment that was not publicly released."We are a Navy that learns from mistakes and the Navy is firmly committed to doing everything possible to prevent an accident like this from happening again," Adm. John Richardson, the chief of naval operations, said in a statement Wednesday. "We will spend every effort needed to correct these problems and be stronger than before."RELATED: Remains of USS John McCain sailors recoveredRichardson ordered a comprehensive review of the accidents, led by Adm. Philip Davidson, head of the Navy's Fleet Forces Command. In a report spanning about 170 pages, Davidson notes that many of the lessons learned can be applied across the Navy. And he recommends the appointment of a senior Navy officer to oversee the implementation of the recommended changes across the fleet, both in the Pacific and -- where needed -- around the world.Proposed changes focused on five main areas: fundamental skills, teamwork, operational safety, assessment procedures and culture. Specifically, the recommendations include beefing up qualification standards for sailors who stand watch -- a key point of failure in the two deadly collisions. Others call for improved navigational skills and certifications for sailors, including better, more sophisticated training on radar, piloting, communications and other high-tech equipment.The report acknowledges the fast-paced operations in the Pacific region, where the Navy is faced with an aggressive China and a growing threat from North Korea's pursuit of nuclear weapons. And it notes that ongoing budget constraints make it difficult to meet the requirements in the very busy Pacific region."The ability to supply forces to the full demand is - and will remain - limited," the report said, adding that funding shortfalls for readiness across the Navy, "did have an impact in putting more pressure to meet increasing demand for Japan-based assets" without additional support from ships based in the United States.Faced with the increasing demands, there was less time for crew members to do needed training or certifications, the report said.The report also noted that despite the growing pressure and pace of operations, there was a "can-do" culture that persisted, and commanders failed to listen to their teams and were unable or unwilling to say no despite the risks."Can-do should never mean must-do so we must continue to encourage our commanders to accept the risks when the benefit to be gained is worth the potential risk of failure," the report said.A number of the recommendations points to fatigue and how the lack of sleep can lead to problems, particularly as sailors stand watch."Sailors need to know when they must succumb to their own fatigue, be proactive about their fatigue management plan, and reach out to leadership," the report said. It also suggested that a mentorship program be set up, assigning experienced commanding officers to help sailors develop leadership skills and focus on seamanship, navigation, team building and operational safety.Davidson's report was submitted to Richardson, and Navy officials said a number of the recommendations are already being addressed. 4693

WASHINGTON (AP) — U.S. officials say the Pentagon is developing plans to withdraw up to half of the 14,000 American troops serving in Afghanistan, marking a sharp change in the Trump administration's policy aimed at forcing the Taliban to the peace table after more than 17 years of war.One official says the troops could be out by summer, but no final decision has been made.President Donald Trump has long pressed to pull troops out of Afghanistan, but was persuaded by Defense Secretary Jim Mattis and others to keep them there to pressure the Taliban and battle a stubborn Islamic State insurgency.Officials say the latest White House push for withdrawal was another key factor in Mattis' decision to resign Thursday.The officials spoke on condition of anonymity to discuss internal deliberations. 809

WASHINGTON, D.C. – Democratic lawmakers in both chambers of Congress are introducing a bill that would ban the federal government from using biometric technology, including facial recognition technology.The bill would also effectively strip federal support for state and local law enforcement entities that use biometric technology. Sen. Ed Markey (D-Mass) is joining forces with Sen. Jeff Merkley (D-Ore.), Rep. Pramila Jayapal (WA-07) and Rep. Ayanna Pressley (MA-07) to introduce the Facial Recognition and Biometric Technology Moratorium Act in the House and Senate.This measure comes amid growing calls from civil rights advocates who say facial recognition technology disproportionately misidentifies non-white individuals. It’s the first bicameral piece of legislation introduced that focuses on the tech since police brutality protests began about a month ago.In a press release, Markey cited a growing body a research that points to inaccuracy and bias issues with these technologies, which pose disproportionate risks to people of color.Markey points to a National Institute of Standards and Technology report on facial recognition tools that found Black, Brown and Asian people were up to 100 times more likely to be misidentified than white male faces.The bill’s introduction comes just one day after the ACLU amplified the story of a Black man in the Detroit area who says he was wrongfully arrested after this kind of technology misidentified him as a man seen stealing ,800 worth of watches.Specifically, the proposed legislation would do the following:Place a prohibition on the use of facial recognition technology by federal entities, which can only be lifted with an act of Congress;Place a prohibition on the use of other biometric technologies, including voice recognition, gate recognition, and recognition of other immutable physical characteristics, by federal entities, which can only be lifted with an act of Congress;Condition federal grant funding to state and local entities, including law enforcement, on those entities enacting their own moratoria on the use of facial recognition and biometric technology;Prohibit the use of federal dollars for biometric surveillance systems;Prohibit the use of information collected via biometric technology in violation of the Act in any judicial proceedings;Includes a private right of action for individuals whose biometric data is used in violation of the Act and allows for enforcement by state Attorneys General; andAllow states and localities to enact their own laws regarding the use of facial recognition and biometric technologies.“Facial recognition technology doesn’t just pose a grave threat to our privacy, it physically endangers Black Americans and other minority populations in our country,” said Markey. “As we work to dismantle the systematic racism that permeates every part of our society, we can’t ignore the harms that these technologies present. I’ve spent years pushing back against the proliferation of facial recognition surveillance systems because the implications for our civil liberties are chilling and the disproportionate burden on communities of color is unacceptable. In this moment, the only responsible thing to do is to prohibit government and law enforcement from using these surveillance mechanisms. I thank Representatives Jayapal and Pressley and Senator Merkley for working with me on this critical legislation.” 3433
