Eventbrite (NYSE: EB) co-founder and CEO Julie Hartz was among the hundreds of CEOs to sign a letter addressed to members of the senate asking a bill be passed requiring background checks on all gun sales and a red flag law allowing courts to issue protection orders in emergency situations when gun owners display warning signs they may be considering violent acts.

“These proposals are common sense, bipartisan and widely supported by the American public,” the letter concludes. “It is time for the senate to take action.”

CEOs from businesses including Twitter, Reddit, and Uber were among the signers of the letter, which was first reported by the New York Times. A total of 46 chief executives representing companies with over 500 employees signed on. A further 110 companies with smaller staffs also saw their executives sign on, including Joshua Kushner, Founder and Managing Partner of Thrive Capital (and brother of Ivanka Trump’s husband Jared Kushner).

“As leaders of some of America’s most respected companies and those with significant business interests in the United States, we are writing to you because we have a responsibility and obligation to stand up for the safety of our employees, customers and all Americans in the communities we serve across the country,” the letter reads. “Doing nothing about America’s gun violence crisis is simply unacceptable and it is time to stand with the American public on gun safety.”

Hartz was the lone executive in the ticketing industry to put her name to the letter, which came in the wake of recent mass shootings at a Walmart in El Paso, Texas as well as others in West Texas and Dayton, Ohio.

Senators returned from recess last week, and some – including GOP Sen. Patrick Toomey (PA) and Joe Manchin (D-WV) and Chris Murphy (D-Conn.) – have been working towards pushing the Trump administration to take up what they consider common sense gun reform in the wake of the recent rash of mass shootings.
