Several Silicon Valley leaders called for increased gun control on Tuesday afternoon after a woman at the headquarters of YouTube shot and wounded three people before taking her own life.

Tech companies have largely avoided the topic of gun control in the United States, but they have previously pushed for progressive stances on other hot-topic issues, ranging from climate change to same-sex marriage and comprehensive immigration reform.

At least three major chief executives took up gun control after the shooting.

“We can’t keep being reactive to this, thinking and praying it won’t happen again at our schools, jobs, or our community spots,” tweeted Twitter and Square CEO Jack Dorsey, sharing Donald Trump's tweet on the shooting.

“It’s beyond time to evolve our policies.”
