Example Input: 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.
Example Output: "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 "

Example Input: Paragraph: "Republican House leaders fanned out on the Sunday shows to defend a stop-gap measure to fund the Department of Homeland Security in their ongoing fight against President Barack Obama's executive action on immigration. They did not stray from talking points. TV audiences Sunday heard one specific number several times as hosts pressed the GOP lawmakers to justify the chaos over funding for the Department of Homeland Security. ""The president said 22 times, 22 times, that he couldn't do what he eventually did,"" House Speaker JohnBoehner said on CBS' Face the Nation. Both Majority Leader Kevin McCarthy and Majority Whip Steve Scalise repeated the ""22 times"" talking point on NBC's Meet the Press and Fox News Sunday, respectively. Even Rep. Jim Jordan, R-Ohio, one of 52 Republicans who opposed a three-week funding plan, used the figure to defend his House Freedom Caucus' actions on CNN's State of the Union. PolitiFact wanted to see where the number comes from and just how accurate it is. What we're talking about The controversy stems from Obama's Nov. 20, 2014, announcement that he would delay deportations of unauthorized immigrants who have lived in the country for more than five years but have children who are citizens or have green cards. More than 4 million people could qualify. An applicant could qualify for a work permit and avoid being deported for three years at a time if he or she can pass a background check and pay a fee. The decision is bound for higher court battles after a Texas federal judge issued a temporary injunction on the action, saying it may have violated procedural rules for using executive power. This action came on top of Obama's Deferred Action for Childhood Arrivals program in 2012, an executive action to protect ""dreamers,"" or people brought here illegally as children and have not committed crimes. That move, too, was viewed by critics as an abuse of power, but supporters said it helped provide a path to citizenship for hundreds of thousands of residents. After Obama's post-midterm elections announcement on immigration, Boehner's office unleashed a Buzzfeed-style blog post detailing ""22 Times President Obama Said He Couldn't Ignore or Create His Own Immigration Law."" What's on Boehner's list Our PolitiFact Texas colleagues dissected Boehner's listfor similar fact-checks of U.S. Rep. Michael McCaul, R-Texas, and Texas Gov. Greg Abbott, the Republican who led the legal challenge of Obama's actions when he was still attorney general. PolitiFact Texas tracked down each of the citations in Boehner's post, comparing what they said Obama said with transcripts and news stories. In a nutshell, the majority of the examples are of Obama saying he did not have power to do more on immigration without Congress. Others, as we'll explain in a moment, say something more nuanced or aren't specific to immigration. We won't go through every quote that supports Boehner's point here, but here are a few we culled from a document created by PolitiFact Texas: In September 2012, Obama was asked if he would follow up his recent protective move for students by doing something similar for non-criminal immigrants such as the parents of U.S.-born children. Obama replied that ""as the head of the executive branch, there's a limit to what I can do we're still going to, ultimately, have to change the laws in order to avoid some of the heartbreaking stories that you see coming up occasionally,"" as in parents deported. (No. 13 on Boehner's list.) At a presidential debate in October 2012, Obama and Mitt Romney were asked: ""What do you plan on doing with immigrants without their green card that are currently living here as productive members of society?"" Obama said: ""I've done everything that I can on my own."" (No. 14 on Boehner's list.) In a January 2013 Telemundo interview, Obama was asked why he couldn't protect mothers living here without authorization from deportation as he had served law-abiding students. ""I'm not a king,"" Obama replied, akin to his response the same month to a similar query from Univision. ""You know, my job as the head of the executive branch ultimately is to carry out the law. And-- you know, when it comes to enforcement of our immigration laws-- we've got some discretion. We can prioritize-- what we do. But we can't simply ignore the law."" (No. 16 on Boehner's list.) So clearly there are examples of Obama saying he couldn't do more with executive action, then later doing exactly that. That's why PolitiFact previously rated Obama's claim that ""my position hasn't changed"" as False. What should not be counted But also included on Boehner's list of 22 are quotes where Obama was either suggesting his executive powers did not have hard limits or was silent on his executive power on immigration. Here are a few problems with quotes included on Boehner's list. In two instances during his 2008 presidential campaign, Obama criticized ""signing statements"" used by President George W. Bush that interpret laws, but he did not bring up immigration. Immigration was also not part of his reply to a question at a 2010 MTV/BET event when he said, ""I can't simply ignore laws that are out there,"" in response to a question about ""don't ask, don't tell."" (Nos. 1, 2 and 5.) In September 2011, with his deferred-action plan on the horizon, Obama reiterated that he cannot just change laws unilaterally in response to a question about possible administrative relief for students who don't have legal residency. But he hinted that there might be room within his authority, saying, ""what we can do is to prioritize enforcement, since there are limited enforcement resources."" (No. 12 on Boehner's list.) Obama's July 2013 Univision interview hit similar notes when he was asked if he could grant amnesty to the undocumented population. He called for a legislative solution and said ""probably not,"" adding, ""I can do some things and have done some things that make a difference in the lives of people by determining how our enforcement should focus."" (No. 18 on Boehner's list.) In August 2014, Obama told reporters he may ""scour our authorities to try to make progress"" without congressional cooperation. Obama said, ""We're going to make sure that every time we take one of these steps that we are working within the confines of my executive power. But I promise you the American people don't want me just standing around twiddling my thumbs and waiting for Congress to get something done."" (No. 22 on Boehner's list.) Asked why Boehner continues to cite 22 examples, spokesman Michael Steel told PolitiFact ""we obviously stand by"" the count. Pressed to explain why, he said, ""Obviously, we're just going to agree to disagree about the '22 times' figure, which we feel is accurate."" The bigger picture Whether the real number is 22, 15 or something less than that is more complicated by the specifics of Boehner's claim. Boehner's claim is Obama said he couldn't do ""what he eventually did."" Experts we talked to noted that Obama was not always so specific in the comments Boehner and his team cited. Boehner's count factors in both instances of Obama talking about how he could not legalize or deport the entire undocumented population as well as more limited executive actions to relieve smaller populations. ""It gives me a headache,"" said Anna O. Law, a CUNY Brooklyn College political science professor, of the post, ""because they're playing semantics."" Alex Nowrasteh, a Cato Institute immigration analyst, said he did not know what to make of the ""very political"" claim. Ultimately, much of it depends on your specific interpretation of each quote. Our ruling Boehner said, ""The president said 22 times, 22 times, that he couldn't do what he eventually did."" Boehner's broader point -- that Obama said one thing about executive action but did another -- is accurate. But he should refrain from the rhetorical flourish of saying Obama said it 22 times. Clarification: This item was updated on March 2, 2015, to better explain the ruling of a federal judge in Texas." Claim: "On immigration, ""the president said 22 times, 22 times, that he couldn't do what he eventually did."
Example Output: "Boehner said, ""The president said 22 times, 22 times, that he couldn't do what he eventually did.""

Example Input: Paragraph: Home to the two largest ports in the country in Los Angeles and Long Beach, California has roughly 1.5 million medium and heavy duty trucks on the road that spew harmful pollutants as they haul freight to warehouses. The state's transportation sector accounts for 41% of all greenhouse gas emissions, a cause of climate change, and is a major source of ozone and particulate matter pollution that can cause respiratory problems. Regulators estimate the new rules would result in roughly 74,000 zero emission trucks on the road in California by 2030, or about 4% of all trucks. California already has a rule requiring car makers to offer for sale specific numbers of clean cars. But Mary Nichols, chairwoman of the California Air Resources Board, said the truck rule would be the first of its kind in the world. The board considered the new rule in a public hearing on Thursday that drew more than 100 public comments. The board won't vote on the proposal until next year. But Thursday was the last chance for advocates and opponents to weigh-in. "Trucks are increasingly a major contributor to air pollution nationwide, but especially in our cities where they are among the largest sources of toxic emissions in vulnerable neighborhoods," Nichols said. If adopted, at least 15% of sales of heavy duty pickup trucks like the Ford F-250 and full size vans like the Chevrolet Express must be zero emission vehicles by 2030. That standard also applies to the heaviest trucks, including tractor trailers. The standard is tougher for box trucks and delivery trucks, mandating at least half of all new sales be zero-emission vehicles by 2030. The rules are part of the state's plan to have 100% zero emission truck sales by 2040. By then, state regulators say the phased-in limits could prevent more than 600 premature deaths due to poor air quality in California. Sales requirements for the heaviest trucks would begin in 2024 and gradually increase until 2030. Sales requirements for pickup trucks would not begin until 2027. The proposed rules continue California's aggressive push on environmental regulations, which already include tougher emission standards on cars and trucks than the federal government imposes and a first-in-the-nation cap-and-trade system that requires big polluters to purchase credits to let them pollute. Most environmental groups support the rule, but they say it is not strong enough. Trucks last longer than passenger vehicles, which is why companies are slower to replace their fleets. While the rules would impact up to 50% of some new truck sales by 2030, it would only result in about 4% of trucks on the road being zero emission vehicles. Andrea Vidaurre, policy analyst for the Center for Community Action and Environmental Justice, said these types of trucks historically are clustered in poorer communities. That includes communities in the Inland Empire, an area next to Los Angeles where warehouses store freight from ports. The group says low-income communities can be most impacted environmental health hazards. "We have so much traffic going in right now just in this area, and the rule currently, it would barely cover it," she said. Jed Mandel, president of the Truck and Engine Manufacturers Association, said he supports efforts to get more zero-emission trucks on the road. But he said making rules "on a naked sales mandate is fundamentally flawed." "Trucks are not cars. Our customers invest capital to purchase vehicles that must return a profit," Mandel said. "We all know today that (zero emission vehicles) are more expensive than traditionally fueled vehicles." Mandel said California regulators should narrow the rule to apply to trucking segments that are "more readily suited to that technology," including school buses and municipal fleet step vans. Claim: California considers requiring zero emission truck sales.
Example Output:
The country's most populous state could become the first to require a portion of new truck sales be electric or "zero emission" vehicles as California grapples with how to clean up its worst-in-the nation air quality.
