Angry Obama Blasts U.S. Gun Politics

President Barack Obama on Thursday angrily said America had made a "political choice" to allow mass shootings like the one in Oregon to occur and blasted the National Rifle Association lobby group for blocking reform of U.S. gun laws. Appearing in the White House briefing room with a grim expression and a frustrated tone, Obama challenged U.S. voters of all political stripes to hold their leaders accountable if they wanted to prevent such tragedies from happening again.
