Left-wing organizations, gun-control groups, and even the media wasted little time in using the senseless massacre in Las Vegas to advance a political agenda on Monday, only hours after a gunman killed at least 58 people and wounded more than 500.

On Sunday night, Stephen Paddock fired an automatic weapon into a crowd across the street from his 32nd-floor room in the Mandalay Bay Resort and Casino. Paddock killed himself as police approached.

The rush to politicize the tragedy was swift.

At Capitol Hill, former Rep. Gabrielle Giffords (D-Ariz.) and her husband, Mark Kelly, noted they were in Virginia to campaign for the Democratic gubernatorial candidate. But they traveled to the Capitol building to hold a press conference in which Kelly called for more gun control.

Giffords was wounded severely by a deranged gunman in a 2011 attack that left six dead.

Failed Democratic nominee for president Hillary Clinton also wasted no time weighing in, tweeting on Monday morning that “the crowd fled at the sound of gunshots. Imagine the deaths if the shooter had a silencer, which the NRA wants to make easier to get.”

Clinton’s tweet about silencers was not uncommon. Many commentators accused the Republican-led Congress of wanting to legalize silencers, not understanding that silencers do not completely suppress loud noise from gun discharges.

Sen. Chris Murphy (D-Conn.), who is weighing a presidential run, put out a statement: “It’s time for Congress to get off its a** and do something.” Murphy did not say what, but he is a fierce advocate for increased gun control measures.

Many on the Left, though, went further than Clinton, Kelly and Giffords.

The New Republic tweeted out a statement based on a 2015 article it published.

“It’s time to ban guns. Yes, all of them,” the official Twitter account of the liberal magazine tweeted.

Cal Perry, the global editor of NBC News, said being a journalist did not restrain him from the new truth, as he saw it.

“Been a journo for a while now,” Perry, 37, tweeted. “It has become impossible to report just ‘facts’ about gun violence. The fact is America needs gun control.”

Vox agreed. The liberal website tweeted out an article, claiming, “Australia confiscated 650,000 guns. Murders and suicides plummeted.”

Hollywood was also crazed all day. The NRA was not spared any restraint.

“The NRA is the country’s most active and successful terrorist organization,” tweeted left-wing comedian Michael Ian Black.

Perhaps one of the cruelest tweets sent out was by the atheist biologist Richard Dawkins of the United Kingdom. Dawkins could not contain his contempt for American culture and its people.

“Durn tootin’, great shootin’. Cool dude sertin’ he’s 2nd Mendment rahts. Hell yeah! Every country has its psychopaths. In US they have guns,” Dawkins tweeted.

But the most consequentially cruel social media post was sent by a CBS attorney, Hayley Geftman-Gold, who wrote, “I’m actually not even sympathetic [because] country music fans often are Republican gun toters.”

Outrage over the Facebook post quickly went viral on social media, and CBS, whose parent company owns MTV and CMT, fired Gold within hours.
