WASHINGTON (AP) — President Donald Trump and his allies are taking what appear to be increasingly frantic steps to subvert the results of the 2020 election, according to law scholars, including summoning state legislators to the White House as part of a longshot bid to overturn Joe Biden’s victory. Trump also has personally called local election officials in Michigan who are trying to rescind their certification votes in Michigan. His legal team has suggested that a judge order Pennsylvania to set aside the popular vote there. And his allies are pressuring county officials in Arizona to delay certifying vote tallies. During a press conference Thursday, the president's personal attorney, Rudy Giuliani, who is working on the campaign's lawsuits, made accusations of voter fraud in a handful of states, and seemed to suggest officials in several big cities were working together. "It’s not a singular voter fraud in any one state. There is a pattern in several states," Giuliani said. "To any experienced prosecutor, it would suggest that there was a plan." However, he did not give any evidence or further details about what led him to believe there was a "plan," other than baseless statements that the cities had "a history of corruption."“It’s very concerning that some Republicans apparently can’t fathom the possibility that they legitimately lost this election,” said Joshua Douglas, a law professor at the University of Kentucky who researches and teaches election law.“We depend on democratic norms, including that the losers graciously accept defeat,” he said. “That seems to be breaking down.”Election law experts see this as the last, dying gasp of the Trump campaign and say there is no question Biden will walk into the Oval Office come January. 1774

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

Walmart is looking to go green by 2040.The world's largest retailer announced they plan to electrify and eliminate emissions from all of its vehicles, including long-haul trucks. They also want to transition to low-impact refrigerants for cooling and powering its equipment to heat its stores, clubs, and data and distribution centers to reach zero emissions."We want to play an important role in transforming the world's supply chains to be regenerative. We face a growing crisis of climate change and nature loss, and we all need to take action with urgency," Doug McMillon, President and CEO of Walmart, said in the release. "For 15 years, we have been partnering to do the work and continually raising our sustainability ambitions across climate action, nature, waste, and people. The commitments we're making today not only aim to decarbonize Walmart's global operations, they also put us on the path to becoming a regenerative company – one that works to restore, renew and replenish in addition to preserving our planet, and encourages others to do the same." By 2030, the company added they plan to manage at least 50 million acres of land and one million square miles of ocean to "help combat the cascading loss of nature threatening the planet."And by 2035, the company said they plan to harvest enough wind, solar and other renewable energy sources to power its facilities with 100% renewable energy. 1419

WASHINGTON (AP) — Defense Secretary Mark Esper on Sunday fired the Navy’s top official over his handling of a disciplinary case involving a Navy SEAL.Esper asked for the resignation of Navy Secretary Richard Spencer and Spencer submitted it Sunday, said the chief spokesman for the Pentagon, Jonathan Hoffman.The firing was a dramatic turn in a long-running controversy involving Navy Chief Petty Officer Edward Gallagher, whose case has been championed by President Donald Trump.Esper also directed that Gallagher be allowed to retire at the end of this month, and that a Navy disciplinary board that was scheduled to hear his case starting Dec. 2 be cancelled, Hoffman said. At Esper’s direction, Gallagher will be allowed to retire as a SEAL at his current rank, Hoffman said.Hoffman said Esper lost trust and confidence in Spencer “regarding his lack of candor” over conversations with the White House involving the handling of the SEAL case.“I am deeply troubled by this conduct shown by a senior DOD official," Esper said in a written statement issued by Hoffman. "Unfortunately, as a result I have determined that Secretary Spencer no longer has my confidence to continue in his position. I wish Richard well." 1225

WASHINGTON (AP) — Contested congressional seats in the nation's suburbs are becoming battlefields, and each party is wielding what it hopes will be a potent weapon. During the pandemic, Democrats are widely returning to the health care theme they used in 2018 to capture House control. In some races, Republicans are promoting the need for law and order after racial justice protests this summer that sometimes turned violent. Even in campaigns where the GOP has chosen a different theme, President Donald Trump's recent focus on law and order can color the debate. Each side has tested its messaging carefully and thinks the other side has chosen a losing issue. 671
