EDISON - As the nation mourns the victims of Colorado's mass shooting last week, many politicians have begun pushing for stronger control over firearms.

Yesterday, a Colorado representative suggested that Congress reinstate an assault weapons ban. Sen. Frank Lautenberg (D-N.J.) is also pressing for a ban. Today, New York's Mayor Michael Bloomberg called on the presidential candidates to come up with gun control plans.

Lautenberg is expected to join other Democrats from California and New York at a press conference tomorrow, to discuss the need for what they call "common-sense gun safety reforms."

Republican representatives have said Congress should get all the facts about the shooting rampage before tackling any legislation on guns.
