WASHINGTON (AP) — The Republican National Convention is aiming to recast the story of Donald Trump's presidency over its four nights of events this coming week. Trump campaign officials involved with the planning process tell The Associated Press that the theme of the convention is “Honoring the Great American Story” and will feature speakers drawn from everyday life as well as cable news and the White House. The primary aim will be to draw a stark contrast with Democratic presidential nominee Joe Biden. Trump is looking to shift the campaign away from being a referendum on a presidency ravaged by a pandemic and economic collapse and toward a choice between vastly different visions of America's future. 719

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

WASHINGTON (AP) — The Supreme Court has ruled that Oklahoma prosecutors lack the authority to pursue criminal cases in a large chunk of eastern Oklahoma that remains an American Indian reservation.The court’s ruling casts doubt on hundreds of convictions won by local prosecutors.The case was argued by telephone in May because of the coronavirus pandemic.The case revolved around an appeal by a Native American man who claimed state courts had no authority to try him for a crime committed on reservation land that belongs to the Muscogee (Creek) Nation.The reservation once encompassed 3 million acres, including most of Tulsa, the state’s second-largest city. 670

WASHINGTON, D.C. – It’s been a strange time everywhere, with COVID-19 upending how people normally live.That includes college students, many of whom are now in a hybrid form of learning, with some on campus and some on a computer at home, like Gregory Carnesi.“Something that I've been experiencing myself, something that I've heard my peers experiencing, is just this feeling of being overwhelmed because everything is online now,” Carnesi said.Carnesi goes to Arizona State University, just one of the campuses in the U.S. where the nonprofit and mental health organization “Active Minds” recently surveyed several thousand college students, to see how they are faring in the time of COVID-19.Here’s what they found:- 1 in 4 students said their depression had “significantly increased” since the start of the pandemic- 89% of the students surveyed said they’re experiencing stress or anxiety- 56% said their daily activity had decreased or significantly decreased.“We have to remind people, ‘you know, you used to walk three miles a day to and from class, or you used to be out on the field running around for soccer practice and you're not doing that right now.’ So how else can you fill that gap and that void for yourself?” said Alison Malmon, founder and executive director of Active Minds.Malmon said it’s also important for colleges and universities to tailor student access to mental health services, since so many are no longer on campus as much.“We are still needing to promote access and we are still needing to give people the supports that they need in the way that they are able to reach them,” Malmon said.Yet, there were some positive findings in the survey.- Nearly two-thirds of students, 66%, said they have been helping support others with their mental health- 77% of those surveyed said they feel optimistic about the futureGregory Carnesi said he is just taking it one day at a time.“I really kind of think the best thing that's worked for me is just having grace and mercy with myself,” he said, “and just doing your best day to day. Even if that best is just getting out of bed and like making yourself breakfast, just like these basic things, that's enough.”If you are in need of mental health resources during the pandemic, click here. 2270
