Two students are injured — one of which is in critical condition — after a school shooting took place Tuesday at Great Mills High School in southern Maryland.The gunman died following the attack according to police officials.Jonathan Freese, a student at Great Mills, told CNN he was in lockdown in his math class. Police were going through classrooms to clear the school, and students will then be escorted out of the school, Freese said."I'm still a little shaken up," he said.Freese said the school had held drills a couple of times for this kind of situation."I didn't really expect for this to happen. I do always feel safe, though, because they always have police at the school," he said.According to CNN's research, there have been 16 confirmed school shootings this year in the United States prior to today.  Great Mills High School has an enrollment of just over 1,500 students, and the student body was about 56% minority students and had a four-year graduation rate of 91%, according to the school's 2015-16 improvement plan.Last week, students at Great Mills High School walked out of class as part of a student-led protest against school violence in the wake of the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida.Al Murray shot video of police responding to the shooting at the high school Tuesday. He says he saw at least one officer run into the building with a shotgun or rifle. 1440

US President Donald Trump on Thursday abruptly canceled his meeting with Russian President Vladimir Putin, which was scheduled to occur during a G20 meeting in Buenos Aires."Based on the fact that the ships and sailors have not been returned to Ukraine from Russia, I have decided it would be best for all parties concerned to cancel my previously scheduled meeting [...] in Argentina with President Vladimir Putin. I look forward to a meaningful Summit again as soon as this situation is resolved!" Trump tweeted en route to the summit.Earlier Thursday, Trump told reporters that he would still "probably" meet with Putin, despite a recent incident in which Russian ships opened fire on and seized three Ukrainian vessels near Crimea."I probably will be meeting with President Putin. We haven't terminated that meeting. I was thinking about it, but we haven't. They'd like to have it. I think it's a very good time to have a meeting. I'm getting a full report on the plane as to what happened with respect to that," he said ahead of his departure on Marine One.Trump added that he will be getting a "full report on the plane" on recent Russian aggression in Ukraine "and that will determine" his course of action. 1222

Two studies recently published in the CDC’s journal indicate COVID-19 can spread on airplanes.In one study, researchers found a woman showing symptoms on a 10-hour flight potentially spread COVID-19 to at least 15 other people on the plane.A 27-year-old businesswoman who lived in London and was from Vietnam started having symptoms, fever and cough, while still in London in late February. She and her sister had visited Italy and other locations in London before the woman flew to Vietnam. Her sister later tested positive for COVID-19.The 27-year-old was one of 21 people sitting in business class on the March 1 flight from London to Hanoi, Vietnam. The woman became more sick once she landed, and isolated in her home. A few days later, she tested positive for COVID-19, as did three people in her house and a friend back in London she had visited before the flight.Researchers quickly tracked down the majority of people who were on the woman’s flight to isolate and trace potential cases.In all, researchers identified 14 additional passengers and one crew member who had COVID-19. The study states 12 of the passengers who tested positive had sat in business class with the 27-year-old woman, and 11 of them were sitting within two seats of her.“First, thermal imaging and self-declaration of symptoms have clear limitations, as demonstrated by case 1 (the woman), who boarded the flight with symptoms and did not declare them before or after the flight. Second, long flights not only can lead to importation of COVID-19 cases but also can provide conditions for superspreader events,” researchers concluded.The second study looked at four people aboard a flight from Boston to Hong Kong on March 9 who all tested positive for COVID-19 after landing in Hong Kong and showing symptoms. Two passengers, a couple, flew in business class. They showed symptoms the day they landed and sought healthcare.The other two cases were flight attendants who served the business class and first class sections of the plane. Both had come into close contact with the couple, and they both developed symptoms a few days after landing.Researchers were able to sequence their viruses and discovered all four had the same strain of COVID-19.Scientists conclude the couple contracted COVID-19 while they were in the U.S. and transmitted it to the flight attendants on the plane.“Passengers and cabin crew do not generally go through the same check-in process at airports before boarding. Although we cannot completely rule out the possibility that (the flight attendants) were infected before boarding, the unique virus sequence and 100% identity across the whole virus genome from the 4 patients makes this scenario highly unlikely,” researchers stated.Although there were no other positive COVID-19 cases reported from this flight, not all passengers were tested or tracked like in the first study.“Our results demonstrate that SARS-CoV-2 can be transmitted on airplanes. To prevent transmission of the virus during travel, infection control measures must continue,” they noted.Both of these studies looked at cases on flights before face coverings were mandatory on flights. They were published in Emerging Infectious Diseases, a journal of the Center for Disease Control and Prevention. 3286

Two influential staffers at the Environmental Protection Agency are leaving the agency, CNN has learned.The security chief for EPA Administrator Scott Pruitt and the leader of the agency's Superfund cleanup program are both departing, according to an internal email and an agency statement, respectively.The exits come just days after Pruitt's management of the agency, including substantial spending on his personal security, travel, and office, came under scrutiny at back-to-back congressional hearings.Pasquale "Nino" Perrotta, the special agent in charge of the Pruitt security detail, announced his departure in a one-sentence email to colleagues on Tuesday morning."It has been a tremendous honor to serve as a special agent for the past 23 years and I wish you all a safe journey ahead as you move forward in both your professional and personal lives," Perrotta wrote.The security team overseen by Perrotta, a former Secret Service agent, has ballooned under Pruitt. Expensive and elaborate practices, such as flying in first class airplane seats, have drawn the attention of watchdogs like the EPA's own inspector general.Rep. Trey Gowdy, a South Carolina Republican, has indicated the House Oversight Committee, which he chairs, is interested in interviewing Perrotta about Pruitt's security and travel. Perrotta's predecessor was pushed aside after refusing to drive Pruitt around Washington using police lights and siren, three sources familiar with the situation told CNN.The EPA has repeatedly defended the spending and security practices as necessary given an increased level of threats against Pruitt. But Senate Democrats say a whistleblower and internal documents cast doubt on the severity of the threats.The EPA did not respond to CNN's request for comment on Perrotta's departure.The other staffer leaving the EPA is Albert "Kell" Kelly, an Oklahoma business associate of Pruitt who was appointed to lead the Superfund cleanup program."Kell Kelly's service at EPA will be sorely missed," Pruitt said in a statement to CNN confirming the departure.Kelly was a senior adviser to Pruitt whose role at EPA involved managing the program that cleans contaminated sites, such as dumping grounds and former industrial or mining facilities.Pruitt appointed Kelly to the position after the Federal Deposit Insurance Corporation, an arm of the federal government that oversees the banking industry, ended Kelly's banking career with a lifetime ban from the industry. The exact nature of his violations were not disclosed.Kelly's former bank, Spiritbank, handled the mortgage for Pruitt's 2004 home purchase in a suburb of Tulsa, Oklahoma. The bank was also involved in the purchase of a minor league baseball team by Pruitt and business partners.The New York Times reported that Kelly's bank also handled the mortgage on an Oklahoma City house Pruitt purchased through a shell company from a lobbyist. One of Pruitt's partners in the shell company also now holds a political appointment at the EPA.Neither Perrotta nor Kelly announced the dates they plan to leave the agency.  3099
