WASHINGTON, D.C. – President Donald Trump has notified Congress that he is formally withdrawing the United States from the World Health Organization (WHO).The Hill and CNN have confirmed that the White House has moved to sever ties with the United Nations agency which continues to lead the world through the COVID-19 pandemic.According to the news organizations, the White House has submitted a notification to the United Nations secretary-general, stating America plans to withdraw from WHO by July 6, 2021. U.S. Sen. Bob Menendez, the top Democrat on the Senate Foreign Affairs Committee, tweeted that Congress was notified of the president’s move Tuesday.Menendez criticized Trump decision and his handling of the coronavirus outbreak as a whole.“To call Trump’s response to COVID chaotic & incoherent doesn't do it justice,” wrote Menendez. “This won't protect American lives or interests—it leaves Americans sick & America alone.” 952

WASHINGTON, D.C. -- On Monday, 17 states and the District of Columbia announced they are suing the Trump administration over the president’s plan to revoke foreign student visas if they only take online classes.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 has also filed a similar lawsuit.Last week, ICE announced international students would have to return home or risk deportation if their universities switch to online-only courses come fall and they cannot find alternative plans. “It’s really hard and really painful,” said Maha AlHamoud, an incoming senior from Saudi Arabia at the University of Washington in Seattle. "No one should have to really make a choice between their health and their education.” At 17%, the University of Washington has one of the highest percentages of the more than 1 million international students in the United States. In 2018, the Institute of International Education estimated they contributed more than billion to the U.S. economy. "This has thrown into a little bit of chaos the reopening plans that higher education institutions had for the fall,” said Theresa Brown, Director of Immigration and Cross Border Policy at the Bipartisan Policy Center. “We could lose a generation of students who come to the U.S. and spend money to support their education, which supports the education of Americans in many instances.” ICE has always required international students take in-person classes if they hope to get a visa. What’s unprecedented in this case, says Brown, is the short time students have to make other arrangements. She says they could apply to other schools that have in-person courses, but that is assuming those universities are welcoming students and their credits would transfer. They could go to other countries like Canada, but that requires starting life over in a country they are not accustomed to.Brown adds foreign-exchange students could also apply to have their temporary status in the United States change, but that requires time, particularly since U.S. Citizenship and Immigration Services intend to furlough 70% of its workforce next month. “This could have long-standing implications,” said Brown. “If you are a foreign national looking where to pursue your education, and you’re looking at the U.S. maybe you think about it again. Maybe you rethink the U.S. is really where you want to be when all these changes come very quickly.” “We really want the institutions that we’ve contributed so much to to protect us,” added AlHamoud. For AlHamoud, the decision on what to do next is particularly tough. During her freshman year, she was diagnosed with a form of blood cancer. It means her decision now is guided as much by her future as it is her health. “I was fighting for my life away from my family and friends,” she said. “But I made that sacrifice for my education hoping I would never have to make that choice again. So now, to be forced into a situation where I have to risk my health to attend my classes seems unfair.” One more caveat, according to Brown, is the ability for these students to go back to their home country if they cannot find a viable alternative. Many, she says, will not accept their own nationals because they have closed off their borders due to the pandemic. 3489

WASHINGTON (AP) — The U.S. has charged two alleged agents of Iran, accusing them of conducting covert surveillance of Israeli and Jewish facilities in the United States and collecting intelligence on Americans linked to a political organization that wants to see the current Iranian government overthrown.Earlier this week, Ahmadreza Doostdar, 38, a dual U.S.-Iranian citizen born in Long Beach, California, and Majid Ghorbani, 59, who has lived and worked in Costa Mesa, California, since he arrived in the United States in the mid-1990s were charged with acting as illegal agents for Tehran. Ghorbani, who was surveilled by U.S. agents, became a legal permanent resident of the United States in 2015.Their arrests come as the Trump administration ratchets up pressure on Iran. The administration recently re-imposed sanctions on Iran to deny Tehran the funds it needs to finance terrorism, its missile program and forces in conflicts in Yemen and Syria.According to a criminal complaint filed in U.S. District Court in Washington, Doostdar allegedly conducted surveillance in July 2017 on Rohr Chabad House, a Jewish student center at the University of Chicago in Hyde Park. The surveillance included security features around the center.Mary Manning Petras, a federal defense lawyer, said a court hearing in the case is set for Sept. 6.Jonathan Greenblatt, national director of the Anti-Defamation League, applauded the arrests and thanked the FBI for "disrupting the alleged intelligence gathering efforts of the Islamic Republic of Iran, a nation with a long record of involvement in, and support for, terror attacks against Jewish and Israeli institutions."In September 2017, Ghorbani allegedly attended a Mujahedin-e Khalq rally in New York City where he photographed people protesting against the current Iranian government.The MEK, despite deep ideological differences, were partners with Ayatollah Ruhollah Khomeini in the 1979 revolution that toppled the U.S.-backed Shah Mohammad Reza Pahlavi. Following the revolution, the MEK quickly fell out with Khomeini and launched an armed revolt against Khomeini's new theocracy. The group is outlawed in Iran and was listed as a terrorist organization by the State Department until 2012.In late 2017, Doostdar returned to the United States from Iran and made contact with Ghorbani in the Los Angeles area. Doostdar allegedly paid Ghorbani about ,000 in cash for 28 photographs taken at the September 2017 rally.The photographs had hand-written annotations identifying the individuals in the photos. These photographs, along with a receipt for ,000, were found concealed in Doostdar's luggage as he transited a U.S. airport on his return to Iran in December 2017.In May, Ghorbani attended the MEK-affiliated 2018 Iran Freedom Convention for Human Rights in Washington. During the conference, Ghorbani appeared to photograph certain speakers and attendees, which included delegations from across the United States. On May 14, Doostdar called Ghorbani to discuss the clandestine ways Ghorbani could use to get the information to Iran."Doostdar and Ghorbani are alleged to have acted on behalf of Iran, including by conducting surveillance of political opponents and engaging in other activities that could put Americans at risk," said John Demers, assistant attorney general for national security.The indictment charged Doostdar and Ghorbani with knowingly acting as agents of the government of Iran without notifying the U.S. attorney general, providing services to Iran in violation of U.S. sanctions and conspiracy. Both defendants were arrested on Aug. 9, pursuant to criminal complaints issued by the U.S. District Court for the District of Columbia.The FBI's field offices in Washington and Los Angeles investigated the case, which is being prosecuted by the national security section of the U.S. Attorney's Office for the District of Columbia and the Counterintelligence and Export Control Section of the National Security Division of the Justice Department.In March, the Justice Department announced charges against nine Iranians accused of working at the behest of the Islamic Revolutionary Guard Corps to steal large quantities of academic data from hundreds of universities in the United States and abroad as well as email accounts belonging to employees of government agencies and private companies. 4374

  

WASHINGTON (AP) — Winter hit U.S. honeybees hard with the highest loss rate yet, an annual survey of beekeepers showed.The annual nationwide survey by the Bee Informed Partnership found 37.7% of honeybee colonies died this past winter, nearly 9 percentage points higher than the average winter loss.The survey of nearly 4,700 beekeepers managing more than 300,000 colonies goes back 13 years and is conducted by bee experts at the University of Maryland, Auburn University and several other colleges.Beekeepers had been seeing fewer winter colony losses in recent years until now, said Maryland's Dennis vanEngelsdorp, president of the bee partnership and co-author of Wednesday's survey."The fact that we suddenly had the worst winter we've had ... is troubling," vanEngelsdorp said.Some bees usually die over winter, but until the past couple decades, when a combination of problems struck colonies, losses rarely exceeded 10%, he said.Bees pollinate billion worth of U.S. food crops. One-third of the human diet comes from pollinators, including native wild bees and other animals, many of which are also in trouble, according to the U.S. Department of Agriculture."We should be concerned on multiple levels," said University of California, Berkeley, agricultural social scientist Jennie Durant, who has a separate study this week on loss of food supply for bees.Year-to-year bee colony losses, which include calculations for summer, were 40.7%, higher than normal, but not a record high, the survey found."The beekeepers are working harder than ever to manage colonies but we still lose 40-50% each year... unacceptable," Swiss bee expert Jeff Pettis, who wasn't part of the survey, said in an email.For more than a decade, bees have been in trouble with scientists blaming mites, diseases, pesticides and loss of food.This past winter's steep drop seems heavily connected to the mites, vanEngelsdorp said. Beekeepers report that chemicals that kill mites don't seem to be working quite as well and mite infestation is worsening, he said. Those mites feed on the bees' fats and that's where the insects store protein and center their immune response.Durant's study in this week's journal Land Use Policy found that changes in food supply in the Midwest's Prairie Pothole Region, a hot spot for honeybee colonies, has been a major factor in losses. That area has lost wetland areas with clover bees feed on.Other areas have been converted to corn and soy crops, which don't feed bees, she said.As bad as the survey numbers are, vanEngelsdorp said, "We're not really worried about honeybees going extinct... I'm more worried that the commercial beekeepers will go out of business." 2695

  

WEST HOMESTEAD, Pa (AP) — After five months of being closed due to the coronavirus, the major movie theaters chains in the U.S. are starting to reopen. AP Film Writer Lindsey Bahr visited the AMC Waterfront 22 in West Homestead, Pennsylvania, just outside of Pittsburgh, on its opening day Thursday. It is one of 113 AMC locations to open nationwide, touting retro movies and retro pricing and strict sanitary policies to entice audiences back to theaters. Many were eager to get back to the theaters, although for most the 15 cent tickets were the main draw. After opening day, back catalog films will cost a ticket. 628
