WASHINGTON — Two days before President Barack Obama's first trip outside Washington to promote his gun-control proposals, the White House tried to settle a brewing mystery when it released a photo to back his claim to be a skeet shooter. Obama had set inquiring minds spinning when, in an interview with The New Republic magazine, he answered “yes” when asked if he had ever fired a gun. The admission came as a surprise to many. “Yes, in fact, up at Camp David, we do skeet shooting all the time,” Obama said in the interview released last weekend, referring to the official presidential retreat in rural Maryland, which he last visited in October while campaigning for re-election. Asked whether the entire family participates, the president said: “Not the girls, but oftentimes guests of mine go up there.” Few could recall Obama ever talking about firing a gun or going skeet shooting “all the time.” The official White House photo released Saturday is dated Aug. 4, 2012. The caption says Obama is shooting clay targets on the range at Camp David. Obama is seen holding a gun against his left shoulder, his left index finger on the trigger and smoke coming from the barrel. He is wearing jeans, a dark blue, short-sleeved polo shirt, sunglasses and earmuffs. The National Rifle Association, which has rejected Obama's proposals, scoffed at the photo. “One picture does not erase a lifetime of supporting every gun ban and every gun-control scheme imaginable,” said Andrew Arulanandam, the influential gun rights lobbying group's spokesman. The NRA opposes Obama's call for Congress to ban assault weapons and high-capacity ammunition magazines and says requiring background checks for all gun purchases would be ineffective because the administration isn't doing enough to enforce existing gun laws. “I have a profound respect for the traditions of hunting that trace back in this country for generations,” Obama said. “And I think those who dismiss that out of hand make a big mistake. Part of being able to move this forward is understanding the reality of guns in urban areas are very different from the realities of guns in rural areas.” Obama said. His gun control measures, which include a ban on assault weapons and high-capacity ammunition magazines, as well as universal background checks for anyone who wants to buy a firearm, have met some resistance on Capitol Hill and from opponents of tighter restrictions on access to guns, including the National Rifle Association, the powerful gun rights lobbying group. In Minneapolis on Monday, Obama plans to make remarks as well as discuss his proposals with local and law enforcement officials during a stop at the police department's special operations center. He's also expected to visit with community members to hear about their experiences with gun violence, the White House said. Obama announced his proposals in mid-January, about a month after the Dec. 14 shooting deaths of 20 children and six adults at an elementary school in Newtown, Connecticut. — Reuters
