WASHINGTON (AP) — President Donald Trump is refusing to publicly commit to accepting the results of the upcoming White House election. In saying that, he's recalling a similar threat he made weeks before the 2016 vote. The president tells “Fox News Sunday” that it's too early to make such an ironclad guarantee, and he scoffs at polls showing him lagging behind Democrat Joe Biden. The Biden campaign says the American people will decide the election and the government “is perfectly capable of escorting trespassers out of the White House.” Trump also is hammering the Pentagon brass for favoring renaming bases that honor Confederate military leaders. Trump says, ”I don’t care what the military says." 713

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 Pentagon says the U.S. will deploy additional troops and military equipment to Saudi Arabia and the United Arab Emirates to beef up security, as President Donald Trump has at least for now decided against any immediate military strike on Iran in response to the attack on the Saudi oil industry.Defense Secretary Mark Esper says this is a first step, and he is not ruling out additional moves down the road. He says it's a response to requests from the Saudis and the UAE to help improve their air and missile defenses.Esper and Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, say details of the deployments will be determined over the coming days. 690

WASHINGTON (AP) — The Trump administration has announced that it will release nearly billion in aid to Puerto Rico to help the island rebuild its electrical grid and repair schools from the devastation of Hurricane Maria three years earlier. In a statement, White House press secretary Kayleigh McEnany said .6 billion would be included for those projects. "Federal funding of .6 billion will allow the Puerto Rico Electrical Power Authority to repair and replace thousands of miles of transmission and distribution lines, electrical substations, power generation systems, office buildings, and make other grid improvements," McEnany said in the statement. "The billion grant for the Puerto Rico Department of Education will focus on restoring school buildings and educational facilities across the island."The announcement comes amid criticism that the assistance was overdue and being released now only for political purposes. The grant comes as President Donald Trump, who has balked at providing assistance to the island territory, and former Vice President Joe Biden court voters in Florida, which is home to a large population of people from Puerto Rico.In a press briefing on Friday, President Trump added that the aid package wasn't the only exciting thing happening in Puerto Rico - it was their pharmaceutical industry."We have spoken to various companies, and they are willing to go there," Trump said. "They want to have a little bit of help, but they are willing to go to Puerto Rico and Puerto Rico is going to be very exciting, let's going to happen. They were on the verge of doing it, and they took away all the incentives. I don't know how they allowed that to happen. It was very bad for Puerto Rico and the people of Puerto Rico. That was done by Democrats, and a Republican is bringing it back."Trump added that Democratic presidential nominee Joe Biden "devastated" the country when he voted to eliminate a critical tax provision in 1996.A year ago, Trump stated in a tweet that Puerto Rico was one of the "most corrupt places on earth," but on Friday, he said it wasn't anymore because he's the best thing that's ever happened to Puerto Rico."I have to say in a very nice way, in a very respectful way, I'm the best thing that ever happened to Puerto Rico," Trump said. "Nobody even close. As a result, the island's economy under the previously mentioned names [Biden and former President Barack Obama], it just absolutely cratered. Biden's vote left the United States at the mercy of foreign suppliers, putting our national security and health at risk."Florida is a critical swing state in the Nov. 3 election. 2654

WASHINGTON (AP) — The Trump administration will begin allowing so-called “Dreamer” immigrants to renew their permits to remain and work in the U.S. for a year while it reviews a Supreme Court ruling and the underlying legality of the Deferred Action for Childhood Arrivals program.A White House official confirmed the announcement Tuesday. Renewals for the Obama-era program, which covers hundreds of thousands of immigrants brought to the U.S. illegally as children, had been halted as the Trump administration pushed to end the program.The Supreme Court ruled earlier this month that Trump failed to follow appropriate procedure when he tried to end the program, but affirmed his ability to do so. The White House has been studying the ruling and devising plans to try again to end DACA — though it was not immediately clear whether the politically sensitive move would be undertaken before November's election.The administration will continue not to accept new applications for the program. 1001
