Within 24 hours of the mass shooting at Marjory Stoneman Douglas High School in Florida, Everytown for Gun Safety, a nonprofit organization backed by billionaire and former New York City mayor Mike Bloomberg, received $750,000 in online donations.
The day after the incident, Bloomberg, a long-time advocate for tighter firearm regulations, urged citizens to take action and "demand common-sense solutions to the gun violence crisis."
After the mass shooting at a country music concert in Las Vegas in October, which left 59 dead and over 500 injured, the former mayor took to Twitter to announce that he would match all donations to Everytown.
"US has a gun violence problem," he wrote. "I'll match every donation. Give now."
The group tracks school shootings and, after some criticism of its methodology, recently revised its tally for this year from 18 down to 17. It has also launched a "five-action plan" for citizens who want to make a difference, which involves pledging to vote, researching which politicians accept NRA donations, registering friends to vote, holding leaders accountable and running for office to champion the cause of sensible gun laws in your community.
When the NRA introduced a bill last year to legalize concealed-carry reciprocity, which would allow gun owners to carry weapons freely between states, the billionaire said he would spend $25 million to fight it, Politico reports. The bill has since made its way through the House of Representatives but is expected to face an uphill battle in the Senate.
