[EX Q]: Given his background  how did  Devin Kelley  get a gun?
 Kelley  previously served in the U.S. Air Force  but was discharged in 2014  an Air Force spokesperson confirmed to Fox News on Monday.
 He  was court-martialed in 2012 for assaulting  his  wife and child.  He  was then sentenced to 12 months in custody before being given a bad conduct discharge.
A 1968 Gun Control Act made it unlawful for a licensed firearms dealer to sell a weapon to any person who is given a dishonorable discharge. But because  Kelley  was discharged on bad conduct  the law was not triggered  Adam Winkler  a professor of law and a specialist in American constitutional law at the University of California at Los Angeles  told Fox News on Monday.
 Kelley  purchased two firearms from two separate Academy Sports + Outdoors stores in San Antonio in 2016 and 2017  respectively  the sporting goods store confirmed to Fox News in a statement on Monday. One of the purchases was allegedly a Ruger model AR-556 rifle.
However   Kelley âs domestic violence charges shouldâve been enough to prevent  him  from purchasing a gun  Winkler said -- but the Air Force most likely didnât report this information to the federal background check system  thus allowing the purchase to go forward.
And Winklerâs prediction was right: The Air Force announced late Monday night that the Holloman Air Force Base Office of Special Investigations -- the base where  Kelley  was stationed -- failed to report  Kelley âs domestic violence conviction to the FBIâs Criminal Justice Investigation Services Division for inclusion in the National Criminal Information Center database. The database is used to conduct background checks on those who want to purchase a gun.
The âbiggest mystery â Winkler said  is how  Kelley  was denied a handgun permit but was allowed to purchase a gun from the sporting goods store. But this information is currently unclear.
Additionally  Texas authorities confirmed Monday that  Kelley  did not have a license to carry. However   he  did have a private security license -- often used by armed and unarmed security guards  personal protection officers  private investigators  and more  according to the Texas Department of Public Safety.

[EX Q]: Rep. Joe Barton   whose nude pic was spread on the internet Wednesday  contacted Capitol Police in regards to the woman who had possession of it â possibly making him a victim of ârevenge porn.â
The woman told the paper that  at that time  she had became aware that  Barton   who is not married  was involved in relationships with other women.
âI want your word that this ends â  Barton  said in a 2015 phone call to the woman.
 Barton  told the paper Wednesday that the phone conversation contained evidence of a âpotential crimeâ against him.
The Dallas Morning News noted that  Barton âs situation could apply to a ârevenge porn lawâ enacted by Texas legislators in 2015.
 He  added that Capitol Police had opened an inquiry on the matter.

[EX Q]: 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.
