Input: Consider Input: Hackers  concealed behind fanciful aliases on the Internet  often appropriate larger-than-life dimensions. In reality  other than in physical proportions  Sabu seemed considerably smaller than life. A defensive-lineman-size man known as Booby  he was raising the two young children of his imprisoned aunt in a public housing project. Court documents showed that Mr. Monsegur  28  paid bills with stolen credit cards and dabbled in drug sales.
 Mr. Monsegur’s  whereabouts are unknown  and  his  lawyers declined to comment.  His  background remains gauzy  but court records and interviews with relatives and neighbors offer an outline.
 He  was born in 1983.  His  father  also named Hector  Monsegur   was arrested in 1997 along with  his  sister  Iris  for selling heroin. Both went to prison for seven years.
While  his  father was locked up   Mr. Monsegur  apparently moved in with  his  grandmother  Irma  who lived in a sixth-floor apartment in the Jacob Riis Houses  a Lower East Side housing project.
School officials said  Mr. Monsegur  attended Washington Irving High School  but left in 2001 without finishing ninth grade. In the transcript of  his  guilty plea   Mr. Monsegur  said that  he  went to college  though it is unclear if  he  actually did.
After  his  release from prison in early 2003  Mr. Monsegur’s father found work with a sanitation company. The aunt  Iris  ran a credit repair company from her Staten Island home. Her involvement with drugs  however  continued. She was arrested again and returned to prison in 2010. By that point she had had two girls. They were entrusted to the care of  the younger Mr. Monsegur   and  he  gained legal custody of them.
Even after  his  aunt left prison last August  her children remained with  Mr. Monsegur .
 He  worked sporadically  including for a few months at OpenPlans  a nonprofit group that tries to improve government through technology.  His  profile on the networking site LinkedIn   which listed  him  as a senior systems administrator there  disappeared on Thursday. A former co-worker described  him  as friendly and competent.
 Mr. Monsegur  was active in computer and hacking circles as far back as the late 1990s  and started a group for local programmers in 2002. “My name is Xavier ”  he  announced  inviting others to join and “integrate their knowledge into one big mass of hairy information.”
 He  soon came to embrace strong antigovernment and anticapitalist ideologies that steered  him  into the hacking world.
In what was identified as a question-and-answer interview with Sabu published in New Scientist magazine last year   he  said that  he  became a hacktivist when  he  was 16.  He  said  he  became disturbed that the Navy was using Vieques Island in Puerto Rico as a bombing range for exercises  and that  he  helped disrupt communications. In 2010   he  said in the interview   he  was drawn to Anonymous   a leaderless  antiauthoritarian movement that has taken up a variety of political causes. The catalyst   he  said  was  his  outrage over the arrest of Julian Assange   founder of WikiLeaks   the whistle-blower site.
In particular   he  became a leader of a splinter group  Lulz Security  or LulzSec  which claimed to attack computer security companies for laughs  or lulz  rather than for financial gain.
Describing  himself    he  said in the interview  “I’m not some cape-wearing hero  nor am I some supervillain trying to bring down the good guys. I’m just doing what I know how to do  and that is counter abuse.” For his online handle he chose Sabu  adopted from a former professional wrestler.
In 2010 and 2011  according to court documents   Mr. Monsegur  participated in a relentless string of online attacks against companies and governments. Targets included Visa  MasterCard   PayPal and Sony .  He  also played a role in attacks on computers belonging to the governments of Tunisia   Yemen   Algeria and Zimbabwe  as well as those of the United States Senate .
Though he was self-taught   Mr. Monsegur  was probably among the most skilled technologists in the bunch. As the “rooter ” federal authorities say   he  was in charge of identifying vulnerabilities of LulzSec targets and creating the attack strategy.
Copies of LulzSec chat logs posted online show that  he  was sometimes wary of getting caught. In one discussion   he  is irate at  his  fellow hackers for revealing the name of a site used in an attack  because it could expose  his  computer’s location. Another participant is deferential: “Mm  okay  ill not say anything further without conferring with you.”

Input: Consider Input: The counties surrounding Hatfield's Ferry -- which are home to multiple universities -- are an example of what hangs in the balance as this debate plays out.
 Last year  when Hatfield's Ferry asked the state for permission to dump scrubber wastewater into the Monongahela River  the Pennsylvania Department of Environmental Protection approved the request with proposed limits on some chemicals.
 Records show  and company officials concede  that Hatfield's Ferry is already dumping scrubber wastewater into the Monongahela that violates the state's few proposed pollution rules. Moreover  those rules have been suspended until a judge decides on the plant's appeal of the proposed limits.
 "It's really important to set a precedent that tells power plants that they need to genuinely clean up pollution  rather than just shift it from the air to the water " said Abigail Dillen  a lawyer with the law firm Earthjustice  which represents two advocacy organizations  the Environmental Integrity Project and the Citizens Coal Council  in asking a Pennsylvania court to toughen regulations on Hatfield's Ferry.
 State officials say they have established appropriate water pollution limits for Hatfield's Ferry  and have strict standards for landfill disposal.
 However  environmental groups have argued in court documents and interviews that Hatfield's Ferry probably will emit dangerous chemicals  and that they fear the state is unlikely to intervene.
 For instance  Pennsylvania has opposed designating the waste from Hatfield's Ferry and other power plants as hazardous. In a statement  the Department of Environmental Protection said the state had "sufficient state and federal laws and regulations at our disposal to control wastewater discharges at levels protective of the environment and public health."
Hatfield's Ferry. "But I see people suffering every day because of this pollution."
 Officials at Hatfield's Ferry say there is no reason for residents to be concerned. They say that lawsuits against the plant are without merit  and that they have installed a $25 million water treatment plant that removes many of the toxic particles and solids from scrubber wastewater. The solids are put into a 106-acre landfill that contains a synthetic liner to prevent leaks.

Input: Consider Input: After the Democratic presidential primaries and caucuses wrapped up last month , Bernie Sanders and his campaign team had a decision to make : pick the next goal . 
Thus far , officials with Hillary Clinton 's campaign and the DNC have been working with Sanders ' team , but the senator has n't won every fight . 
Sanders also fought for an endorsement of single-payer health care and a new tax on carbon , but the party was n't prepared to go along with these provisions , either . 
The Washington Post 's Greg Sargent noted late last week , shortly before the platform draft was released , that Sanders has won "some big victories ," and that 's absolutely true . 
As of late last week , there can be little doubt that Sanders has succeeded : as MSNBC 's Alex Seitz-Wald reported , Dems are moving forward with "what is almost certainly the most progressive platform in the party 's history ." 
That said , as an objective matter , Sanders has had at least as much of an impact on the Democratic platform as any second-place finisher in modern times . 
And yet , over the holiday weekend , Sanders wrote an op-ed in the Philadelphia Inquirer arguing that his victories are n't enough : the platform , he said , "needs to be significantly improved ." 
On Wall Street , the platform lays out a number of reforms proposed by Clinton , Sanders and other Democrats , and states the party "will not hesitate to use and expand existing authorities as well as empower regulators to downsize or break apart financial institutions ," it states . 
And while it 's very likely that Sanders will follow through on that commitment , it 's unclear when , exactly , he 'll start pursuing this goal . 
There can be little doubt that many of these provisions and more -- reforming the carried-interest loophole , postal banking , the industry ties of Federal Reserve board members -- can be attributed directly to the Sanders campaign 's role in negotiating the terms of the platform . 
We 'll never know for sure , but part of me wonders what the presidential race would look like right now if Sanders , once the race for the Democratic nomination wrapped up , had quickly endorsed Clinton , helped unite progressive voters , and focused his energies less on the platform and more on becoming one of the party 's leading anti-Trump voices -- all while positioning his movement as a powerful contingent in Democratic politics .


Output: Bernie Sanders
