Amy Schumer is determined to help put an end to gun violence.

The comedian and vocal gun control advocate posted a new series of tweets after the horrific mass shooting in San Bernardino, California, on Wednesday, that left at least 14 people dead, and 17 more injured.

"This is absolutely heartbreaking-all my love to everyone in San Bernardino especially the first responders," Schumer tweeted. "These shootings must stop."

The 34-year-old Trainwreck star followed up the outpouring and love with several calls to actions for something to be done about guns, writing, "It doesn't have to be this way. Join the movement and help us #endgunviolence," while linking to Everytown, a website devoted to curbing gun violence through legislation.

Schumer further called for her fans to text their congressional representatives over the issue, writing, "Tell congress directly that we want background checks on ALL gun sales. Do it now! I did!"

"I did not write take away all guns. Just for background checks. Take a breath and help stop gun violence #stopgunviolence," Schumer continued.

"U.S. Senate vote today on gun violence. Will your senators stop dangerous people from getting guns? Ask them," the actress also encouraged her followers to do.

Beyond promoting action, Schumer respectfully responded to a fan questioning gun control by arguing the laws are already pretty strong, writing, "Yes you are right. But you can buy online or gunshows or in a parking lot too. We can do better."

This is not the first time Schumer has used her platform to advocate for stronger gun regulations. In addition to mocking the glorification of guns during her Saturday Night Live appearance in October, she has on two occasions teamed up with her cousin, U.S. Senator Chuck Schumer, in press conferences stressing the need for universal background checks, along with the abolition of loopholes that allow purchasers to skirt regulations.

"These shootings have got to stop. I don't know how else to say it," she said in August, speaking out about a shooting that occurred during a screening of her movie, Trainwreck, the previous month.

"No one wants to live in a country where a felon, the mentally ill or other dangerous people can get their hands on a gun with such ease," she told reporters at the time. "The critics scoff and say, 'Well, there's no way to stop crazy people from doing crazy things,' but they're wrong.”
