White House Press Secretary Sarah Huckabee Sanders suggested Hillary Clinton had no business calling out the National Rifle Association in the hours after Sunday night's Las Vegas mass shooting.

'It's very easy for Mrs. Clinton to criticize and to come out, but I think we need to remember the only person with blood on their hands is that of the shooter,' Huckabee Sanders told reporters from the podium. 'This isn't the time to go after individuals or organizations,' she added.

Clinton was the first high-profile Democrat out of the gate calling for new gun control measures, specifically knocking the NRA for backing legislation that would make it easier for Americans to purchase silencers.

'Our grief isn't enough. We can and must put politics aside, stand up to the NRA, and work together to try to stop this from happening again,' the former Democratic nominee for president said.

Hillary Clinton was the first high-profile Democrat to lash out at the National Rifle Association in the aftermath of last night's mass casualty Las Vegas shooting

Press Secretary Sarah Huckabee Sanders said Monday that it wasn't the time to 'go after individuals or organizations' pushing back on Hillary Clinton's call to 'stand up to the NRA'

Hillary Clinton started by offering condolences, but then turned to the National Rifle Association in her Monday morning tweets

Clinton suggested enacting the law could have led to more victims.

'The crowd fled at the sound of gunshots,' Clinton noted. 'Imagine the deaths if the shooter had a silencer, which the NRA wants to make easier to get.'

Huckabee Sanders called any discussion of gun control policy premature.

'I think we can have those policy conversations, but today is not that day,' she said.

Last night's shooting is already the deadliest in modern American history, outranking last summer's Pulse nightclub shooting that left 49 victims and the gunman dead.

Now, 58 lay slain, at the hands of 64-year-old Stephen Paddock, who injured 515 more.

Clinton had started her tweets by offering your typical condolences.

'Las Vegas, we are grieving with you—the victims, those who lost loved ones, the responders, & all affected by this cold-blooded massacre,' she wrote.

But then she pivoted and took on the NRA.

Clinton was the first high-profile Democrat to go to bat for better gun control measures in the aftermath of the shooting.

She recently came out with her campaign memoir What Happened and vowed she wouldn't go away.

While Democrats are generally on board with such measures, Clinton's fellow party members including House Minority Leader Nancy Pelosi, D-Calif., Senate Minority Leader Chuck Schumer, D-N.Y., and former President Barack Obama didn't immediately smack around the NRA.

In a morning statement, Pelosi simply offered prayers and strong words.

'Horrified and heartbroken by the awful tragedy in #LasVegas last night. Praying for those lost, wounded & waiting for news from loved ones,' the top House Democrat also tweeted.

Her counterpart in the US Senate made a similar statement.

'Deeply saddened for the people of Las Vegas and the country. We will keep the victims & their families in our hearts,' Schumer wrote.

'I commend the Las Vegas 1st responders, the SWAT team & the regular ppl who acted quickly & saved lives. Thank you,' the Senate minority leader added.

Obama, who pushed for better gun control measures in the aftermath of the Sandy Hook massacre, and also guided the nation through the Pulse nightclub massacre, which had been the most bloody until now, also left the NRA out of it.

'Michelle & I are praying for the victims in Las Vegas. Our thoughts are with their families & everyone enduring another senseless tragedy,' the ex-president tweeted.

But as several hours went by, calls for stronger laws came again.

Sen. Chris Murphy, D-Conn., whose state was haunted by the Sandy Hook murders, asked for this gun violence to stop.

'It is positively infuriating that my colleagues in Congress are so afraid of the gun industry that they pretend there aren't public policy responses to this epidemic,' Murphy said in a statement.

'There are and the thoughts and prayers of politicians are cruelly hollow if they are paired with continued legislative indifference,' he continued.

'It's time for Congress to get off its a** and do something,' Murphy demanded.

Two of the biggest advocates for better gun control measures – former Rep. Gabby Giffords, D-Ariz., and her husband Mark Kelly – held a press conference on Capitol Hill Monday afternoon.

Giffords was shot in the head in January 2011 during a 'Congress on Your Corner' constituent meeting at a Tuscon, Arizona Safeway.

She recuperated some and resigned from Congress, with she and Kelly at the helm of the gun control group Americans for Responsible Solutions ever since.

Giffords still talks in halted speech, telling the crowd Monday, 'The nation is counting on you.'

Kelly explained that he and Giffords had been in the Washington, D.C., area to campaign for Virginia gubernatorial candidate Ralph Northam, the Democrat.

They hastily put together a press conference asking members of Congress to 'summon the courage' to act.

'Thoughts and prayers are important. But they are not enough,' Kelly said. 'Your thoughts and prayers aren't going to stop the next shooting. Only action and leadership will do that.'

He pushed back on criticism that calling for action on Capitol Hill today was disrespectful to the victims.

'You know if not now, when?' Kelly said. 'Gabby and I have all of those folks in our thoughts and prayers,' he added, but then noted again, 'today is the time.'
