WASHINGTON (REUTERS) - House Democrats rallied on the steps of the US Capitol on Wednesday (Oct 4) to urge for gun control legislation in wake of the mass shooting in Las Vegas.

They were joined by former Democratic congresswoman Gabby Giffords, who was shot in the head by a gunman in 2011 in Tucson, Arizona.

The Las Vegas shooting has reignited a debate in the United States about whether more gun control legislation might have prevented what happened. Republicans who control the US Congress have shown little inclination to respond to Democratic calls for gun measures.
