Hollywood Demands Gun Control in Wake of Las Vegas Shooting: 'What Will It Take, #Congress, For You to Act?'
13 Concert and Nightclub Tragedies Before Route 91 Harvest Festival

Julianne Moore, George Takei and Gigi Hadid among celebrities speaking out in favor of gun control after at least 50 die in Las Vegas.

The Las Vegas shooting on Sunday night that left over 50 people dead and over 400 injured is sparking another round of gun control debate in Hollywood.

After news spread about the horrific terrorist attack during Jason Aldean's headlining performance at the Route 91 Harvest Festival, Gigi Hadid, Gina Rodriguez, Julianne Moore, Emmy Rossum and Sheryl Crow were among the stars joining Hillary Clinton on social media in advocating for lawmakers to act by placing more restrictions on firearms in America.

Following the attack, carried about by 64-year-old white man Stephen Paddock, "#GunControlNow" quickly became one of the top Twitter trends Monday morning, as did "Sandy Hook," "stopthehate," "#shooting" and "The NRA." Paddock, who open fired on the 22,000-person crowd from the 32nd floor of the Mandalay Bay Hotel, was found dead by officers when they stormed the room.

The resurgence of gun control advocacy after a mass shooting in America is nothing new. Expect the conversation to be a hot topic for the entire week as those falling on both sides of the issues duke it out on social media, opinion columns, talk shows and cable news.

"Can we discuss the loss of rights of people going to a concert because of the lack of assault rifle regulations?" Crow, a musician, tweeted.

Moore tweeted, "I mourn this senseless loss of life. What will it take, #Congress, for you to act?"
