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

WASHINGTON (AP) — Christmas-season gridlock descended on the nation's capital Saturday like an unwelcomed present just before the holiday as America's elected leaders partially closed down the government over their inability to compromise on money for a wall along the U.S.-Mexico border.Congressional Democrats are refusing to accede to President Donald Trump's demands for billion to start erecting his long-promised barrier, and the stalemate is a chaotic coda for Republicans in the waning days of their two-year reign controlling government.Vice President Mike Pence, Trump son-in-law and senior adviser Jared Kushner and White House budget chief Mick Mulvaney left the Capitol late Friday after hours of bargaining with congressional leaders produced no apparent compromise.RELATED: Government shutdown: Who will get furloughed if a spending bill is not signed?Mulvaney sent agency heads a memorandum telling them to "execute plans for an orderly shutdown." He wrote that administration officials were "hopeful that this lapse in appropriations will be of short duration." That expectation was widely shared.With negotiations expected to resume, the House and Senate scheduled rare Saturday sessions. House members were told they would receive 24 hours' notice before any vote. "I am in the White House, working hard," Trump said Saturday on Twitter.The impasse blocks money for nine of 15 Cabinet-level departments and dozens of agencies, including the departments of Homeland Security, Transportation, Interior, Agriculture, State and Justice.RELATED: Government shutdown: Constructive talks are happening, McConnell saysThe disruption affects many government operations and the routines of 800,000 federal employees. Roughly 420,000 workers were deemed essential and will work unpaid just days before Christmas. An additional 380,000 will be furloughed, meaning they will stay home without pay.Federal employees already were granted an extra day of vacation on Monday, Christmas Eve, thanks to an executive order that Trump signed this past week. The president did not go to Florida on Friday as planned for the holiday.Those being furloughed include nearly everyone at NASA and 52,000 workers at the Internal Revenue Service. About 8 in 10 employees of the National Park Service were to stay home; many parks were expected to close.RELATED: President Trump tweets that government shutdown will last for a 'very long time' if wall not fundedThe Senate passed legislation ensuring that workers will receive back pay. The House seemed sure to follow suit.Some agencies, including the Pentagon and the departments of Veterans Affairs and Health and Human Services, were already funded and will operate as usual.The U.S. Postal Service, busy delivering packages for the holiday season, will not be affected because it's an independent agency. Social Security checks will be mailed, troops will remain on duty and food inspections will continue.Also still functioning will be the FBI, the Border Patrol and the Coast Guard. Transportation Security Administration officers will continue to staff airport checkpoints and air traffic controllers will be on the job.Trump has savored the prospect of a shutdown over the wall for months. Last week he said he would be "proud" to close down the government, and on Friday said he was "totally prepared for a very long" closure. Many of Congress' most conservative Republicans welcomed such a confrontation, but most GOP lawmakers have wanted to avoid one because polling shows the public broadly opposes the wall and a shutdown over it.RELATED: What to expect if there's a partial government shutdownInitial Republican reaction to the shutdown was muted. Among the few GOP lawmakers who issued statements as it began were Sens. Lisa Murkowski of Alaska, who expressed disappointment at the lack of a deal, and Lamar Alexander of Tennessee. "This is a complete failure of negotiations and a success for no one," Alexander said.The Democratic leaders, Rep. Nancy Pelosi of California and Sen. Chuck Schumer of New York, said in a statement that Trump "threw a temper tantrum and convinced House Republicans to push our nation into a destructive Trump Shutdown in the middle of the holiday season."Trump had made clear last week that he would not blame Democrats for any closure. Now, he and his GOP allies have spent the past few days saying Democrats bear responsibility.The president said now was the time for Congress to provide taxpayers' money for the wall, even though he long had claimed Mexico would pay for it. Mexico repeatedly has rebuffed that idea."This is our only chance that we'll ever have, in our opinion, because of the world and the way it breaks out, to get great border security," Trump said Friday. Democrats, who opposed major funding for wall construction, will take control of the House on Jan. 3.Looking for a way to claim victory, Trump said he would accept money for a "Steel Slat Barrier" with spikes on the top, which he said would be just as effective as a "wall" and "at the same time beautiful."Senators had approved a bipartisan deal earlier in the week to keep the government open into February and provide .3 billion for border security projects, but not the wall. But the House rebelled and approved a package temporarily financing the government but also setting aside .7 billion for the border wall.A test vote in the Senate on Friday showed that Republicans lacked the 60 votes needed to advance the House plan. That jump-started negotiations between Congress and the White House. 5581

WASHINGTON — Ivanka Trump has been deposed by attorneys alleging that President Donald Trump’s 2017 inauguration committee misused donor funds. A new court filing, first reported by CNN Wednesday, notes that Ivanka Trump, the president’s oldest daughter and a senior White House adviser, was interviewed Tuesday by attorneys from the Washington, D.C., attorney general’s office. The office has filed a lawsuit alleging waste of the nonprofit’s funds, accusing the committee of making more than million in improper payments to the president’s Washington, D.C., hotel for event space during the week of the inauguration in 2017.In a Thursday morning tweet, Trump confirmed that she had met with the D.C. attorney general in connection with the investigation. She said she shared an email with investigators in which she asked staff at the hotel to charge a "fair market rate" for hotel rooms."This 'inquiry' is another politically motivated demonstration of vindictiveness & waste of taxpayer dollars," Trump said. 1027

Viewers to Friday’s White House news briefing heard press secretary Kayleigh McEnany claim that Paw Patrol had been canceled.“We saw a few weeks ago that Paw Patrol, a cartoon show about cops, was canceled. COPS was canceled. Live PD was canceled,” McEnany said. "Lego halted sales of their Lego City Police Station. It's really unfortunate."But a Nickelodeon spokesperson refuted that claim Friday afternoon, saying that the show has not been canceled.Also, Lego is still selling Lego City Police Stations on its website.Paw Patrol is a children’s cartoon that shows dogs in rescue situations. The cartoon includes dogs working as police officers, firefighters and other rescue type jobs. The show claims to be the No. 1 ranked TV program for pre-school children.While Live PD and COPS succumbed last month to pressure to cancel amid national unrest over policing and racial injustice, Paw Patrol has remained on the air. There were a few social media posts made that claimed that the show depicts policing in a positive light, and thus should be canceled.The show also caught flack for joining other TV shows in a social media blackout on June 7, which said “muted and listening.”President Donald Trump’s son Eric said that the people who were calling to cancel Paw Patrol are “truly insane.”Besides Paw Patrol remaining on Nickelodeon, the cartoon series is slated to have a full-length movie. The movie is slated for an August 2021 debut. 1450

WASHINGTON (AP) — A Justice Department investigation finds that Yale University is illegally discriminating against Asian American and white applicants, in violation of federal civil rights law. Yale denies the allegation, calling it “meritless” and “hasty.” The findings were detailed in a letter to the college’s attorneys Thursday. The letter was obtained by the Associated Press. It marks the latest action by the Trump administration aimed at rooting out discrimination in the college application process. The Justice Department says the two-year investigation concluded that Yale “rejects scores of Asian American and white applicants each year based on their race, whom it otherwise would admit.” 711
