According to the Washington Times:
Campaign finance records show that Maine Moms Demand Action for Gun Sense, which is affiliated with the billionaire former New York mayor’s group, donated about $433,000 to the gun ownership organization when it dissolved this year.”
“Other top donations came from Washington resident and venture capitalist Nicholas Hanauer — who gave $125,000 and is donating large sums to gun safety ballot measures in other states this year — and Maine resident and author Stephen King, who has given $25,000.”
“Before it dissolved, the Moms group was almost exclusively funded by Everytown. Of the $1.4 million collected since its August 2015 formation, $1.3 million came directly from Everytown.”
“Meanwhile, three opposition groups — including the National Rifle Association — have collected just under $45,000, according to the latest campaign finance records available.”
Hanauer was one of the driving financial forces behind the Washington gun control effort two years ago, and this year, his group is pushing another measure, Initiative 1491. This one pushes emergency protection order disarmament, and is being challenged by people concerned about due process.
