Washington state is on track to become one of the strictest states in the U.S. on gun laws.
Initiative 1639, a sweeping measure to beef up gun-regulations, passed Tuesday with 60 percent of the vote, Seattle's Q13 Fox reported.
Campaign Manager Stephen Paolini, 22, said the measure’s passing sends “a message to our elected officials: Enough is enough.”
“My generation has been defined by gun violence. We have been defined by continued and repeated inaction by our elected officials,” Paolini told a crowd of supporters after the measure passed.
Alan Gottlieb of the Bellevue, Wash.-based Citizens Committee for the Right to Keep and Bear Arms, said opponents will sue to block I-1639.
Other critics say I-1639 violates their Second Amendment rights and will be ineffectual in preventing mass shootings.
