White House spokesman Jay Carney said Tuesday that he has not discussed a new NRA game with the president.

The iPhone and iPad app "NRA: Practice Range," released Sunday, has caused controversy because of its release close to a month after the Sandy Hook shootings. The first-person shooter game is labeled appropriate for users aged four and older.

In the game, players can use a variety of guns, including assault weapons. But the targets are all dummies or discs, not living creatures. In between rounds, gun safety tips are featured.

In his fiery press conference responding to the Newtown, Conn. massacre, NRA Vice President Wayne LaPierre blamed violent video games in part for what he described as an increasingly violent culture.
