Q: Paragraph: Most Americans are familiar with the exploits of John Glenn, a former U.S. Marine Corps pilot who, as one of the original Mercury 7 astronauts, was transformed into a national hero after becoming the first American to orbit the Earth on 20 February 1962. Later in life he represented Ohio in the United States Senate for twenty-four years, and in 1998 he became the oldest person to go into space when he flew on a Space Shuttle Discovery mission in 1998. Much less well known is John Glenn's wife, the former Annie Castor, whom Glenn had known since childhood and married when he was a 21-year-old combat pilot during World War II. In February 2012, the fiftieth anniversary of Glenn's orbital flight prompted CNN contributor Bob Greene to pen the article referenced above about the Glenns' lengthy marriage (currently 68 years) and Annie's long battle to overcome a terrible stuttering problem which had she had struggled with since she was a little girl, an affliction she finally managed to overcome at the age of 53. Annie Glenn began speaking out publicly about her lifelong struggle with her speech impediment in the early 1980s, discussing the subject on national television and in the press, crowning her achievement by making speeches on behalf of her husband as he campaigned for the 1984 Democratic presidential nomination. A 1982 Los Angeles Times article on the subject of Annie Glenn's speaking out about her disability reported that: Annie Glenn is one of the country's estimated 2 million people who suffer what may be the most misunderstood disability: stuttering. Until she underwent a new form of intensive, live-in treatment three years ago at the Communications Research Institute at Hollins College in Roanoke, Va., Mrs. Glenn could not speak well enough to call the plumber, order a meal in a restaurant or go by herself with her injured child to a hospital emergency room, much less give a campaign speech for her husband. Although she still stutters slightly and speaks haltingly, Mrs. Glenn can perform all those once impossible tasks. She even gives campaign speeches, maybe not with as much polish as other wives, but certainly with more pluck. At a private athletic club in Cleveland, 150 people attending the annual meeting of the Cleveland Hearing and Speech Center sat in silent attention at their dinner tables as their speaker told them something really quite remarkable. "For the first time in my life," said Annie Glenn, age 62, "I can carry on a conversation." It wasn't so long ago that Mrs. Glenn, classified as an 85% stutterer, would have found it impossible, even, to travel by airplane from Washington to Cleveland by herself unless she wrote down what she wanted for the airline employee at the ticket counter. She told the audience of such an experience and how the men wrote notes back, thinking she was deaf. During the slow, agonizing process in which stutterers try to force out sounds, often with their hearts beating at an accelerated rate, their palms sweating, their cheeks blushing and their heads bobbing, Mrs. Glenn has been laughed at. Store clerks have reacted by pointing an index finger at the head and moving it in circles (the "crazy" sign), or by asking if she were cold when her jaw would quiver, or saying quite simply, "Lady, I haven't got all day." Sometimes Mrs. Glenn would walk away rather than continue the ordeal of shopping. Her husband had to make all the telephone calls to repairmen and friends. Her neighbors had to call the doctor when her children became ill and go to the hospital with her to talk with the doctors. Mrs. Glenn had undergone several traditional speech therapies but experienced little or no improvement until she enrolled herself for two different sessions at the Hollins Institute, most recently in September of 1978. The therapy lasts 11 hours a day for three weeks. After taking the therapy twice, Mrs. Glenn still sees a therapist twice a month at Walter Reed Hospital in Washington, and she practices every day on the telephone. She makes several calls every morning. There is a sign next to her phone at home that says "Take a full breath, relax your throat, keep the sound moving." "She talks to her buddies all over the world," John Glenn said, pretending to resent the phone bills. "This is a dramatic, new life for her." A 1983 Associated Press article on the same subject read (in part): For 53 of her 63 years, Annie Glenn was a prisoner of her own tongue, a stutterer who tripped over eight out of every 10 words, relying on facial expressions to make a point. She disciplined her two children, she recalls, "with my eyes and my hand." Today, the wife of Ohio Sen. John Glenn has broken through a sound barrier. "Being able to talk to people is something I could never do," she says. "My life is like a dream." In numerous conversations [on the campaign trail] throughout a day that started before dawn and ended long after sunset, [the couple] talked about Mrs. Glenn's newly acquired ability to speak fluently and the impact of her lifetime of stuttering on their marriage, children and career. "John would make all my telephone calls," Mrs. Glenn says, shooting a stern look at her husband as he reached for a third chocolate bar. "I would try to go shopping but couldn't ask the clerk what I wanted, so I would hunt and hunt. A lot of the time I'd go out of the store empty-handed because I couldn't find what I wanted." It was in 1974, after Mrs. Glenn enrolled in a speech program at Hollins College near Roanoke, Va., that her speech improved noticeably. But she didn't keep up the daily therapy sessions or return for refresher courses, and she regressed. After a second session at Hollins and a program of daily therapy, Mrs. Glenn is making speeches. Claim: Article details efforts of John Glenn's wife to overcome stuttering.

A: "Annie was never silent to me," [Glenn] says. "But to see her at this age branch out to things she was interested in but could never participate in "

Q: Paragraph: Senators Richard Burr and Thom Tillis issued statements saying they will vote against Dourson to serve as head of EPA's Office of Chemical Safety and Pollution Prevention. Environmentalists and Senate Democrats have vehemently opposed Dourson, a toxicologist with close ties to the chemical industry. That means only one more Republican "no" vote would likely be needed to torpedo his nomination. Moderate GOP Sen. Susan Collins of Maine told reporters Thursday she is also leaning against supporting Dourson, but has not yet made a final decision. The White House and EPA did not respond to requests for comment Wednesday or Thursday. Despite the fact he hasn't yet been confirmed by the Senate, Dourson has already been working at the agency as a senior adviser to EPA Administrator Scott Pruitt. The agency's press office did not respond to emails seeking how much he is being paid. The Associated Press reported in September that Dourson has for years accepted payments for criticizing studies that raised concerns about the safety of his clients' products, according to a review of financial records and his published work. Past corporate clients of Dourson and of a research group he ran include Dow Chemical Co., Koch Industries Inc. and Chevron Corp. His research has also been underwritten by industry trade and lobbying groups representing the makers of plastics, pesticides, processed foods and cigarettes. Burr and Tillis, both of whom are considered reliably pro-business conservatives, cited Dourson's past work and worries among their home-state constituents about tainted drinking water in opposing his nomination. "Over the last several weeks, Senator Tillis has done his due diligence in reviewing Mr. Dourson's body of work," said a statement from Tillis' office. "Senator Tillis still has serious concerns about his record and cannot support his nomination." Marine veterans and their families blame decades-old contamination of wells at a North Carolina base with solvents and dry-cleaning chemicals for infant deaths and serious health problems that include cancer. More recently, concerns have been raised about undisclosed discharges of chemicals used to manufacture Teflon and GoreTex into the Cape Fear River, a source of municipal drinking water for Wilmington and other southeastern North Carolina communities. Dourson worked at the EPA for more than a decade, leaving in 1994 as the manager at a lab that assessed the health risks of exposure to chemicals. The following year, he founded Toxicology Excellence for Risk Assessment, a private toxicity evaluation nonprofit organization that tests chemicals and produces reports on which chemicals are hazardous in what quantities. Dourson's views toward industry are consistent with others Trump has selected as top federal regulators. Among them is Pruitt, who in March overruled the findings of his agency's own scientists to reverse an effort to ban chlorpyrifos, one of the nation's most widely used pesticides. Court records show Dourson and his work have often been called on when his corporate clients are seeking to fend off lawsuits. DuPont was accused of polluting a West Virginia town with Perfluorooctanoic acid, or PFOA, a chemical that the company's internal tests had long ago concluded was toxic. Corporate officials discussed hiring Dourson as part of a strategy to defend themselves. Dourson led a team that found in 2002 that PFOA levels up to 150 parts per billion were safe, a level higher than was found in testing of 188 private wells and springs. That was also well above the 1 part per billion that Dupont's own scientists had concluded could be considered safe years before. The EPA now says that only 70 parts per trillion of PFOA are acceptable or only 0.05 percent of what Dourson's team said was safe. DuPont and a former subsidiary, Chemours Co., later paid $761 million to settle 3,550 lawsuits stemming from its use of the chemical. Chemours is the company whose spills of a chemical called GenX, a replacement for PFOA, are now at issue in North Carolina's Cape Fear River. "I will not be supporting the nomination of Michael Dourson," said Burr, the state's senior senator. "With his record and our state's history of contamination at Camp Lejeune as well as the current GenX water issues in Wilmington, I am not confident he is the best choice for our country." The stand was quickly praised by environmental advocacy groups that rarely find common ground with the two Tarheel Republicans. "No one who has spent decades arguing on behalf of the chemical industry for weaker safety standards should be charged with reviewing chemicals for the EPA," said Scott Faber, a senior vice president for government affairs at the Environmental Working Group. "It would be like putting an arsonist in charge of the fire department." ___ Follow Associated Press environmental reporter Michael Biesecker at http://twitter.com/mbieseck Claim: Trump EPA nominee opposed by GOP senators from NC.

A:
North Carolina's two Republican senators say they oppose President Donald Trump's pick to oversee chemical safety at the Environmental Protection Agency, putting Michael L. Dourson's nomination at serious risk.
