Today's edition of quick hits:
* What a nightmarish story: "[Franklin County] Sheriff Bill Overton, speaking at a news conference in Moneta, Virginia, said a criminal homicide investigation is ongoing into the deaths of WDBJ reporter Alison Parker, 24, and news photographer Adam Ward, 27. The two journalists were shot and killed while doing a live report Wednesday morning." The shooter is also dead.
* Democratic presidential hopeful Hillary Clinton, while "praying for the victims' families," also insisted today, "We must act to stop gun violence, and we cannot wait any longer."
* Afghanistan: "Two American service members were killed Wednesday in an apparent 'insider' attack by an Afghan soldier at a military base in Afghanistan's southwestern Helmand province, U.S. and Afghan officials reported."
* The wild ride continues: "U.S. stocks emphatically ended their six-day losing streak on Wednesday, with the Dow Jones closing up more than 600 points and posting its third-biggest point gain ever."
* Arizona: "A judge ruled Wednesday that a hospital assessment that pays for the expansion of the state's Medicaid program was constitutional because it did not require a supermajority vote of the Legislature to be enacted."
* Will Republicans continue to treat this as a legitimate news outlet? "Breitbart News reacted to reports that two Virginia journalists were shot to death on-air by a disgruntled former co-worker by publishing an article with the headline, 'Race Murder In Virginia: Black Reporter Suspected Of Executing White Colleagues - On Live Television!'"
* Russia: "Russia ordered several internet service providers to block Wikipedia throughout the country after the volunteers who run the user-generated online encyclopedia refused to delete an article -- then abruptly reversed its decision less than 24 hours later."
* Politico reported the other day that President Obama referred to opponents of the Iran deal as "crazies." That's not really what happened.
* What a great story: "A young cancer survivor sent President Barack Obama a moving letter thanking him for keeping a promise made during a 2007 campaign stop -- a promise the boy says saved his life."
