WASHINGTON (AP) — Senate Majority Leader Harry Reid says Congress must have a meaningful conversation and debate on how to change laws to stop gun violence.

Reid, in a floor speech Monday, did not specify any particular legislation he had in mind to prevent violence like the murder of 20 school children in Connecticut.

The Nevada Democrat said Congress has not done enough to protect Americans, especially children.

He said the debate should take place in the coming weeks and days.

The Senate began its session Monday with a moment of silence for the Connecticut victims.
