WASHINGTON (AP) — The Trump administration says people would drive more and be exposed to increased risk if their cars get better gas mileage, an argument intended to justify freezing Obama-era toughening of fuel standards.Transportation experts dispute the arguments, contained in a draft of the administration's proposals prepared this summer, excerpts of which were obtained by The Associated Press.The excerpts also show the administration plans to challenge California's long-standing authority to enact its own, tougher pollution and fuel standards.Revisions to the mileage requirements for 2021 through 2026 are still being worked on, the administration says, and changes could be made before the proposal is released as soon as this week.RELATED: California sues over plan to scrap car emission standardsThe Trump administration gave notice earlier this year that it would roll back tough new fuel standards put into place in the waning days of the Obama administration. Anticipating the new regulation, California and 16 other states sued the Trump administration in May.Overall, "improvements over time have better longer-term effects simply by not alienating consumers, as compared to great leaps forward" in fuel efficiency and other technology, the administration argues. It contends that freezing the mileage requirements at 2020 levels would save up to 1,000 lives per year.New vehicles would be cheaper — and heavier — if they don't have to meet more stringent fuel requirements and more people would buy them, the draft says, and that would put more drivers in safer, newer vehicles that pollute less.RELATED: EPA moves to weaken Obama-era fuel efficiency standardsAt the same time, the draft says that people will drive less if their vehicles get fewer miles per gallon, lowering the risk of crashes.David Zuby, chief research officer at the Insurance Institute for Highway Safety, said he's doubtful about the administration's estimate of lives saved because other factors could affect traffic deaths, such as automakers agreeing to make automatic emergency braking standard on all models before 2022. "They're making assumptions about stuff that may or may not be the same," he said.Experts say the logic that heavier vehicles are safer doesn't hold up because lighter, newer vehicles perform as well or better than older, heavier versions in crash tests, and because the weight difference between the Obama and Trump requirements would be minimal.RELATED: President Trump, California clash over key issues"Allow me to be skeptical," said Giorgio Rizzoni, an engineering professor and director of the Center for Automotive Research at Ohio State University. "To say that safety is a direct result of somehow freezing the fuel economy mandate for a few years, I think that's a stretch."Experts say that a heavier, bigger vehicle would incur less damage in a crash with a smaller, lighter one and that fatality rates also are higher for smaller vehicles. But they also say that lighter vehicles with metals such as aluminum, magnesium, titanium and lighter, high-strength steel alloys perform as well or better than their predecessors in crash tests.Alan Taub, professor of materials science and engineering at the University of Michigan, said he would choose a 2017 Malibu over a heavier one from 20 years earlier. It's engineered better, has more features to avoid crashes and additional air bags, among other things. "You want to be in the newer vehicle," he said.RELATED: Nearly every governor with ocean coastline opposes Trump's drilling proposalAn April draft from the Trump administration said freezing the requirements at 2020 levels would save people ,900 per new vehicle. But the later draft raises that to ,100 and even as high as ,700 by 2025.Environmental groups questioned the justification for freezing the standards. Luke Tonachel, director of the clean-vehicle program at the Natural Resources Defense Council, said the risk from people driving more due to higher mileage is "tiny and maybe even negligible."Under the Trump administration proposal, the fleet of new vehicles would have to average roughly 30 mpg in real-world driving, and that wouldn't change through 2026.California has had the authority under the half-century-old Clean Air Act to set its own mileage under a special rule allowing the state to curb its chronic smog problem. More than a dozen states follow California's standards, amounting to about 40 percent of the country's new-vehicle market.Asked if he thinks a freeze in U.S. mileage standards is warranted, EPA acting administrator Andrew Wheeler told a small group of reporters at EPA headquarters last week, "I think we need to go where the technology takes us" on fuel standards.Wheeler did not elaborate. Agency spokespeople did not respond when asked specifically if the EPA acting chief was making the case that modern cars could be both fuel efficient and safe.Wheeler also spoke out for what he called "a 50-state solution" that would keep the U.S car and truck market from splitting between two different mileage standards.The Department of Transportation said in a statement that the final fuel economy standards would be based on sound science. The department cautioned that a draft doesn't capture the whole picture of the proposed regulation.The draft said a 2012 analysis of fuel economy standards under the Obama administration deliberately limited the amount of mass reduction necessary under the standards. This was done "in order to avoid the appearance of adverse safety effects," the draft stated.___Krisher reported from Detroit. 5642

We all know exercise is great for your health, but a new study shows that there is one type of exercise that will improve your mental health the most. A new study by the Journal of Lancet Psychiatry found that group fitness classes helps with your overall mental health, more than solo exercises.  Thomas Obershaw not only takes group fitness classes, but he also teaches them. He goes to Transform Colorado to take their Lagree Fitness classes. He not only gets a killer workout in, but he says a group setting gives him the motivation to put in the hard work. "I love group fitness so much, because I do believe there is power in numbers," says Obershaw.Life can be stressful. Work can get in the way of a lot of things, including spending time with people. That's one of the reasons Obershaw loves to workout with others, because he doesn't want to feel isolated. "When you show up to a group fitness class, and you see everyone around you struggling, you don't feel alone," says Obershaw.The recent study also found those who exercise between 30 to 60 minutes a day have the best mental health. "When you show up and get to release all this stress and strife of everyday life, that's in your head, this monkey brain you have all day," says Obershaw. "When you get to forget about that for 45 minutes, it does something to you chemically and physically." The study also found those who participated in group activities had one less poor mental health day a month and felt a 43 percent improvement mentally. If you're looking to get the most out of your group exercise, team sports were rated number one for having the most mental health benefits. Another, popular group fitness class is cycling. They say the high intensity cardio mixed with motivation also gave great results. "It's easy to stay in bed, lay in bed, but exercise releases endorphins," Obershaw says. "It's science; when you release those endorphins that's great for your mind and it's great for your psyche." Whether you enjoy group fitness or not, it is scientifically proven the more you exercise, the greater the benefit.  2203

We don’t often think of racism impacting people’s health. But Dr. Amber Johnson has made a career of studying how the two issues are intertwined.“We’re in Los Angeles at this moment. Black women are the most rent-burdened in this area, so you think about having the stresses of being in a low-class environment and having to deal with racism and cope with racism," said Dr. Johnson, a professor at California State Long Beach who focuses on racism in health care. "And a lot of times, there’s feelings of isolation and loneliness all those things contribute to early physiological wear and tear on our body. Our bodies are literally wearing down."Dr. Johnson says racism is ingrained in our health system. One reason she says implicit bias, which are attitudes or stereotypes that affect our understanding and our decisions, even if we don’t realize it.“These implicit biases are passed down through practice, beliefs, experimentation, all these other things that really contribute to these implicit biases that we see, that are, that become very apparent when black people present in health care fields,” she explained.But systemic racism may start before you get to the doctor's office. Some experts say it begins with access.“People of color face long-standing and persistent disparities in health and healthcare, and these span across a wide array of measures,” said Samantha Artiga, the Director of the Disparities Policy Project at the Kaiser Family Foundation. Artiga's job is to look at how people of different races, genders, and classes are treated differently within the health care system. She says disparities in health care and health outcomes start with access to care and works their way up through every imaginable facet of life.“People of color are more likely to be uninsured than white individuals. That translates into increased barriers to access and care because they’re more concerned about costs, may have less access to a provider, not have a huge source of care outside of the emergency room,” she explained.Those healthcare woes can then be tied directly to jobs because 159 million Americans of all races get health insurance through their employers.But experts say the root of the race and health care problem lies in the kinds of jobs filled mostly by Black and Brown Americans. This is because they are more likely to be working in industries that may not offer coverage to their employees, or when it is offered it may not be affordable to individualsResearch from the National Institute of Health and the Center for American Progress shows African Americans in the US are less likely to have health care coverage than white people. That may be why Black women are more likely to be overweight. Black children are more likely to have asthma. Black adults are more likely to have hypertension. Cancer kills Black people at a higher rate than any other group. Black people are more likely to be diabetic than white people. Black babies die at more than double the rates of all other races in the US, and Black women die more than three times as often during childbirth as white women.Those are just some of the disparities that exist.Over and over again while researching this story, we heard about another major healthcare issue for many people of color: a shortage of doctors, nurses, and other health care workers that look like them, sound like them and have similar life experiences.“Black physicians make up 4-5 percent of all doctors practicing nationwide, whereas, Blacks make up 13 percent of the US population,” said Dr. Leon McDougle, the president of the National Medical Association, a national group that represents Black physicians in the US. He says when he was in medical school, he didn’t have a lot of Black classmates.“I went to medical school here at the Ohio State in the mid-’80s and there weren’t many faculty doctors that looked like me, and when you saw a Black doctor, it almost became a mental image. So, that was inspiration for me to say this has to change,” said Dr. McDougle.He says in 2020 when he sees patients of color, it has an impact on them and they have an impact on him and his students.“More than half the time when I see patients, I have a medical student, and not too uncommonly, that student will be African-American or LatinX. And to just hear the patients give them, cause most of my patients are African American, and to hear them help uplift them in their pursuit of becoming a physician, I hear that all the time,” he said.So, there is hope that there will be more healthcare workers of color, but there is still a long way to go. According to the Association of American Medical Colleges, over the last five years, the number of Black medical students has gone up about one percent, from 6 percent to 7 percent.Many say that's not enough.And the people working for change say the opportunity to make it happen is now.“It’s hard work to move systems and move structures and I just hope we don’t miss the opportunity that is presented at this current time, in terms of the attention, focus, and movement to do something about it,”“It’s not just for me to say I did this, but it’s for me, it’s for my mom, for my grandmother, it’s for my daughter. That’s four generations of black women that I’ve seen negatively affected by racism,” said Artiga.“It’s killing Black people. It’s killing, it’s killing us,” said Dr. Johnson. 5410

WASHINGTON (AP) — The United States and Israel tracked and killed a senior al-Qaida operative in Iran earlier this year, in a bold intelligence operation that came as the Trump administration was ramping up pressure on Tehran. Four current and former U.S. officials say the operative, Abu Mohammed al-Masri, al-Qaida’s No. 2, was killed by assassins in the Iranian capital in August. Two of the officials, one current and one former, say Israeli agents carried out the operation. Two others say Israel had been involved in surveillance but could not say definitively who pulled the trigger when al-Masri was gunned down in a Tehran alley on Aug. 7, the anniversary of the 1998 bombings of the U.S. embassies in Nairobi and Dar es Salaam. 745

WASHINGTON (AP) -- The Supreme Court has rejected the Trump administration's bid to throw out a California immigrant-sanctuary law that limits local police cooperation with federal immigration authorities.The justices' order Monday leaves in place lower court rulings that upheld the law.The administration said the 2017 state immigrant-sanctuary measure conflicts with federal immigration law and makes it harder to deport people who are in the country illegally.California Attorney General, Xavier Becerra, released a statement that said in part: "We’re protecting Californians’ right to decide how we do public safety in our state. The Trump Administration does not have the authority to commandeer state resources. We’re heartened by today’s Supreme Court decision."The San Diego County Sheriff's Department sent ABC 10News the following statement:"The Supreme Court decision not to hear a legal challenge to California's sanctuary law does not change or impact the operations of the San Diego County Sheriff's Department. Our agency is already in full compliance with SB54.We do not enforce immigration laws. We prioritize community relationships and want all residents to feel safe when reporting crimes or coming forward as a witness to criminal acts."The Sheriff's Department also sent the following documents related to the law:https://www.sdsheriff.net/documents/sb54.pdf [sdsheriff.net]https://www.sdsheriff.net/documents/SDSD%20Values%20Act%20Information%20Page.pdf [sdsheriff.net] 1502
