While many across America were mourning the horrific mass shooting at a California bar Thursday, the liberal activists of Hollywood were already busy using the shooting to promote gun control.

“We live in a war zone, because Republicans do nothing about gun laws, while they see people being shot every day. They do nothing,” comedian Chelsea Handler roared.

Author Stephen King called for “gun control now.”

Meanwhile, actor Josh Gad declared that America is “on a hamster wheel of insanity.”

“Another day of grief. Another day of outrage. Another day of families unnecessarily learning their loved ones are dead. But, don’t worry, I remember from all of the other times we’ve done this…’guns aren’t the problem.'”

Hamilton creator Lin-Manuel Miranda re-tweeted Gad, adding that his “heart is dust from being broken.” Miranda also included a link to the activist group Everytown for Gun Safety, which works to enact gun control.

These celebrity screeds came after at least 12 people had been shot and killed at a Southern California bar late Wednesday. The alleged shooter was identified as David Ian Long, according to reports, a veteran of the U.S. Marine Corps.

THOUSAND OAKS IS 5 min FROM WHERE WE GO TO MOVIES🙏🏻A NICE FAMILY TOWN.WILL NRA EVER CARE ABOUT PPL BEING KILLED & HELP INACT SENSIBLE GUN LAWS, HUGE % OF NRA MEMBERS BELIEVE LAWS MUST BE PASSED — Cher (@cher) November 8, 2018

WATCH THIS VIDEO. Republicans in power watch this and say “Oh well, your son should’ve had a gun. Sorry. Too bad.” That’s their response. I think the Republicans in power are complicit in every mass shooting that we’ve had. Maybe on THEIR deathbeds, they’ll feel some regret.

It’s still a comment on our country the violence we’ve created with our love and celebration of gun culture…we also do not take care of our vets at all…stop trying to explain away the culture of violence that gun accessibility has created https://t.co/rajBiwk1Ly — Ellen Pompeo (@EllenPompeo) November 8, 2018

White Male. Radical Domestic Terrorism. #GunControlNow — Morgan J. Freeman (@mjfree) November 8, 2018

These horrific terrifying mass shootings are male hate gone amok. Hate against women, against minorities, against community, and always and primarily, against themselves. What is making men in America so hateful? So suicidally blinded with rage and loneliness? #GunControlNow — Josh Fox (@joshfoxfilm) November 8, 2018
