WASHINGTON, D.C. -- The Trump administration has rescinded a rule that would have required international students to transfer schools or leave the country if their colleges hold classes entirely online this fall because of the coronavirus pandemic.The administration’s decision was announced at the start of a hearing in a federal lawsuit in Boston brought by Harvard University and the Massachusetts Institute of Technology.The announcement brings relief to thousands of foreign students who had been at risk of being deported from the country, along with hundreds of universities that were scrambling to reassess their plans for the fall in light of the policy.The rule was facing opposition from state governments across the country. Monday, 17 states and the District of Columbia filed a lawsuit against the Trump administration in an effort to stop the policy.Along with D.C., the lawsuit was filed by these states: Colorado, Connecticut, Delaware, Illinois, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, and Wisconsin. California also filed a similar lawsuit. 1160

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 D.C. (KGTV) -- Did President Trump appoint the man who killed a beloved lion to a wildlife conservation panel?In 2015, Minnesota dentist Walter Palmer killed Cecil the Lion in Zimbabwe. The incident sparked outrage over international trophy hunting.President Trump did not name Palmer to a wildlife conservation panel, however, the President did name ten members of the trophy-hunting lobby group “Safari Club International” to the panel.The group has roughly 50,000 members, including Palmer. 512

  

WASHINGTON (AP) — The official serving as President Donald Trump’s eyes and ears at the Justice Department has been banned from the building after trying to pressure staffers to give up sensitive information about election fraud and other matters she could relay to the White House, three people familiar with the matter tell The Associated Press.Heidi Stirrup, an ally of top Trump adviser Stephen Miller, was quietly installed at the Justice Department as a White House liaison a few months ago. She was told within the last two weeks to vacate the building after top Justice officials learned of her efforts to collect insider information about ongoing cases and the department’s work on election fraud, the people said.Stirrup is accused of approaching staffers in the department demanding they give her information about investigations, including election fraud matters, the people said. They spoke on condition of anonymity because they were not authorized to publicly discuss the matter.The effort came as Trump continues to level baseless claims that he won the election and alleges without evidence that massive voting fraud was responsible for his defeat to President-elect Joe Biden.Stirrup had also extended job offers to political allies for positions at some of the highest levels of the Justice Department without consulting any senior department officials or the White House counsel’s office and also attempted to interfere in the hiring process for career staffers, a violation of the government’s human resources policies, one of the people said.The Justice Department declined to comment. Attempts to reach Stirrup for comment were not immediately successful. 1686

  

WASHINGTON, D.C. – President Donald Trump officially named Amy Coney Barrett as his Supreme Court nominee over the weekend.What we know about herBarrett has long been rumored to be a possible Supreme Court justice and before being nominated, she was believed to be the favorite among conservatives to take the seat vacated by the late Justice Ruth Bader Ginsburg.Barrett is currently serving on the 7th U.S. Circuit Court of Appeals and she spent several years as a professor at Notre Dame Law School, where she also earned her own law degree.Barrett is believed to be a true conservative, having formerly clerked for the late right-wing beacon Justice Antonin Scalia. If appointed to the high court, her rulings would likely be in line with her mentor. When accepting Trump’s nomination on Saturday, she said Scalia’s “judicial philosophy is mine, too.” Scalia helped popularize the idea of originalism, which follows the idea that courts should interpret the Constitution as it was originally intended by those who wrote it.In recent years, Barrett has sided with conservatives on cases involving immigration, guns rights and abortion.In a 2017 article, Barrett took issue with Chief Justice John Roberts’ ruling to keep the Affordable Care Act intact in 2012. Writing for the Norte Dame Law Journal, Barrett said “Chief Justice Roberts pushed the Affordable Care Act beyond its plausible meaning to save the statute."Barrett is also by legal standards young at only 48 years of age. Recently, both political parties have opted for younger justices to ensure they can serve for decades.Barrett and her husband, Jesse Barrett, a former federal prosecutor, have seven children, including two adopted from Haiti. They live in South Bend, Indiana, but the judge was born in New Orleans, Louisiana, where she was raised Catholic.If appointed to the Supreme Court, conservatives would hold a 6-3 majority over their liberal colleagues.Senate Republicans plan on swiftly moving forward with Barrett’s nomination, despite being weeks away from the general election.The confirmation process is sure to be a contentious one, with Democrats expected to highlight the possibility of the Affordable Care Act being dismantled and the fate of a woman’s right to choose in question.Watch Barrett accept the Supreme Court nomination: 2326
