The massacre in 2012 in the Sandy Hook elementary school lead Chris Murphy, a Democrat Senator from Connecticut, to act and propose strongly to end the armed violence, something he relentlessly kept doing since.
"There are a lot of days that I wish I hadn't heard things I heard, seen things I heard that day," he once said, describing the shooting of Sandy Hook.
Following the recent shooting in the Robb elementary school in Texas, Uvalde, this time he "begged" his colleagues to take real measures.
At the same time, he has been quite persistent when it comes to gun violence, warning his colleagues over and over again on this issue over the course of ten years after the Sandy Hook incident.
"It's been 74 shootings since Sandy Hook," he warned, in a speech in 2014.
"Having come through the experience of Newtown, I've had enough. It's been four years and nothing has been done," he said in another statement in 2016.
A year later, he can be seen again warning his colleagues saying that "Because we have done nothing, the mass shootings continue."
Following weeks, he elaborated on the issue saying, "There is no other country where 80-90 people die from guns."
Three years after that, in a similar speech, he said that "This is a choice made by the United States Senate; to sit on our hands and do nothing, while kids die."
Nearly 10 years after the Sandy Hook, he once again asked for concrete action following the Uvalde shooting.
"Our kids are living in fear every time they set foot in a classroom because they think they're going to be the next,"
"What are we doing?" he asked his colleagues.
"Why do you spend all this time running for the United States Senate. Why do you go through all the hassle of getting this job, of putting yourself in a position of authority, as the slaughter increases, as our kids run for their lives, we do nothing."
