Former Mayor Michael Bloomberg's gun control group Everytown for Gun Safety contributed another $360,000 to I-594, the universal background check measure on this year's ballot that would mandate background checks on all gun sales.
The October 20 contribution brings the group's total contributions to the measure to $3.16 million when you include their earlier contributions plus the separate committee they've established to support the measure which has raised $860,000.
The pro-I-594 campaign proper has raised $9.7 million , according to the Public Disclosure Commission's latest reports.
Other big contributors include Nick Hanauer ($1.3 million), Connie Ballmer ($1.07 million), and Bill and Melinda Gates ($1 million).
The competing measure, I-591, which would prevent local regulations from exceeding federal gun control regulations—meaning no universal background checks—is primarily funded by the NRA and has raised $1.2 million.
They're also raising money explicitly against I-594 and have raised about $600,000.
