President Barack Obama has suffered a large setback in his bid to curb gun violence in the America after the US Senate failed to reach the 60 votes needed to pass a plan to expand background checks for firearms.
Mark Barden, whose son Daniel was among those killed in the Newtown massacre, has said families of the victims are heartbroken at the Senate's blocking of gun ownership legislation but will continue to campaign for stronger weapon controls.
He issued an emotional plea at the White House after a plan aimed at expanding background checks for gun buyers failed to receive enough support in a vote.
With President Obama looking on, Mr Barden said: "We always knew this would be a long road. We don't have the luxury of turning back."
The father of a seven-year-old boy who died in the massacre at Sandy Hook elementary school has told reporters that "what happened in Newtown could happen anywhere" and that "no one should have to feel (his) pain".
Flanked by President Barack Obama, Mark Barden said 12 families of the victims of the Sandy Hook shooting had come to Washington with "a sense of hope".
Mr Barden said the suggested reform to gun control by two US senators was "a common sense proposal backed by 90% of Americans. We will return now disappointed but not defeated"
After a bipartisan deal which would have increased back ground checks on people who wanted to buy guns failed to pass the US Senate, Republican Senators have been presenting alternative suggestions.
One proposal put forward by Senator Charles Grassley of Iowa focuses on improving mental health records for gun owners and funding "improved school safety measures". But controversially it would also expand some gun owner rights by allowing interstate arms sales.
Rather than restricting the rights of law-abiding Americans, we should be focusing on keeping guns out of the hands of violent criminals, which this legislation accomplishes.
The only way to stop violent crime is to stop violent criminals."
The Senate Democratic Leader Harry Reid has accused the NRA and gun lobby of "shameful scare tactics", after an amendment which would have expanded background checks on people wanting to buy guns, failed to secure enough of the vote to be put into law.
Opponents of the measure say that said the proposals were an example of government overreach that would infringe on the constitutional right to bear arms.
We must strike a better balance between the right to defend ourselves and the right of every child in America to grow up safe from gun violence.
If tragedy strikes again if innocents are gunned down in a classroom or a theatre or a restaurant I could not live with myself as a father, as a husband, as a grandfather or as a friend knowing that I didn't do everything in my power to prevent.
