Here are the gun control policies that majorities in both parties support

In a statement on Monday, Giffords, who was the target of an assassination attempt by a gunman in 2011, sent her condolences to the Las Vegas victims, praised first responders, and called for an end to gun violence.

Almost 12,000 people have been killed in gun violence as 273 mass shootings have occurred so far in the United States in 2017, according to the Gun Violence Archive, a not-for-profit corporation that tracks gun-related violence in America.

"How many more dead bodies will it take to wake up this Congress?"

Sen. Richard Durbin of IL, the Senate's No. 2 Democrat, pushed Congress to pass a universal background checks bill and "commonsense gun laws" to help prevent the next mass shooting. "We are not going to knee-jerk react to every situation", he said.

Experts believe that the incident, which US President Donald Trump termed as an "act of pure evil", is unlikely to bridge the bitter differences between the pro- and anti-gun control law lobbies in the country. A group of Democratic lawmakers asked Ryan to remove the silencer bill from the House calendar indefinitely. The bills do not have the 60-votes needed to overcome an anticipated Democratic filibuster in the Senate.

Democrats are planning a rally on the steps of the Capitol on Wednesday morning to call attention to Republicans' inaction on gun control.

Over two years ago, he had released a comprehensive plan to deal with gun violence like the public health epidemic that it is, the lawmaker said, adding that the solutions should not be hard. She added that the investigation was ongoing, "and it would be premature for us to discuss policy when we don't fully know all the facts or what took place last night".

Broad majorities of more than eight in 10 Republicans and Democrats (and independents who lean toward each party) support blocking people who are mentally ill and people on federal no-fly or watch lists from buying guns.

Ryan also told reporters that the focus ought to be on mental health rather than gun restrictions.

"One of the things we've learned from these shootings is that often, underneath this, there is a diagnosis of mental illness", Ryan said. I think it's important that as we see the dust settle and we see what was behind some of these tragedies that mental health reform is a critical ingredient to making sure we can try and prevent some of these things that have happened in the past.

Rep. Mark Amodei, R-Nev., who represents the northern part of the state, said it is a "humbling time" for Nevadans but did not mention the need for any specific legislative response.

In her speech on the floor of the US House of Representatives yesterday, Jayapal said the American people were exhausted of being outraged, sending thoughts and prayers, seeing men, women and children die "because the gun lobby does put profit over people". "But I think right now, it's just that humility - thoughts and prayers to those folks that were affected, both those that are here and those that are gone".
