Here's a portion from from the president's speech:
"As a country, we have been through this too many times. Whether it is an elementary school in Newtown, or a shopping mall in Oregon, or a temple in Wisconsin, or a movie theater in Aurora, or a street corner in Chicago, these neighborhoods are our neighborhoods and these children are our children. And we’re going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics."
Read between the lines. He's going to lead the charge for gun control in the coming weeks and months. He's going to pressure the new Congress to take action.
Also, the U.N. is going to revisit the small arms treaty in March. This is a different way he can go after guns. He only needs the Senate to ratify it. We all know they will pass any kind of anti gun legislation they can get their hands on.
