The photo shows the president, just after pulling the trigger, firing at clay targets in August, The Washington Post reported.
The president's shooting abilities became an issue when he was asked in an interview with The New Republic if he had ever used a gun.
"Yes, in fact, up at Camp David, we do skeet shooting all the time," he responded.
Rep. Marsha Blackburn, R-Tenn., suggested on CNN this week the president was being deceptive.
"If he is a skeet shooter, why have we not heard of this? Why have we not seen photos?" she asked. "I think he should invite me to Camp David, and I'll go skeet shooting with him. And I bet I'll beat him."
"One picture does not erase a lifetime of supporting every gun ban and every gun control scheme imaginable," the National Rifle Association said Saturday in a statement issued to NBC News.
