Top GOP Donor Won’t Back Candidates Unless They Support Assault Weapons BanFollowing Wednesday’s shooting massacre at a Florida high school, a top Republican political donor has taken a stand for gun control ― by tightening his purse strings.Following Wednesday’s shooting massacre at a Florida high school, a top Republican political donor has taken a stand for gun control ― by tightening his purse strings.Businessman Al Hoffman Jr. told the New York Times that he “will not write another check” for candidates and political groups that don’t support a ban on assault weapons. The Florida-based former ambassador to Portugal has donated millions to GOP candidates and political groups over the years, reported the paper.“For how many years now have we been doing this — having these experiences of terrorism, mass killings — and how many years has it been that nothing’s been done?” said the 83-year-old, who announced his decision in an email to several Republican leaders, including Florida Gov. Rick Scott and former Gov. Jeb Bush. “It’s the end of the road for me.” Al Hoffman Jr. has donated millions to Republicans. He says he’s finished unless the party changes on guns. https://t.co/tFuDnmeQFY — NYT Politics (@nytpolitics) February 17, 2018 Gun violence survivors, activists and others have been calling for stricter gun control laws this week in the wake of Wednesday’s mass shooting at Marjory Stoneman Douglas High School, which left 17 people dead. The alleged gunman, 19-year-old Nikolas Cruz, used an AR-15-style semiautomatic rifle in the attack.In 2013, Sen. Dianne Feinstein (D-Calif.) introduced a bill that sought to ban military-style assault weapons including guns like the AR-15. The bill, which failed to pass in the Senate, was similar to the 1994 ban on assault weapons that expired in 2004.Republican lawmakers have mostly expressed little interest this week in pursuing new gun control legislation. In a Saturday tweet, President Donald Trump blamed Democrats for the lack of gun control reform.Hundreds gathered to protest against guns on the steps of the Broward County Federal courthouse on February 17, 2018 in Fort Lauderdale, Florida.

The NRA spent $30 million supporting Trump’s campaign in the 2016 presidential election, according to the Center for Responsive Politics. The group spent millions more that year supporting other Republican candidates, including Sen. Marco Rubio (R-Fla.) and Sen. Roy Blunt (R-Mo.). When asked by Vox this week if Congress should act to tighten gun laws in the wake of the Florida shooting, Blunt said that he didn’t know enough about the attack to “know if there’s a proper response or not.”Rubio said on Thursday that he didn’t believe stricter gun laws would be effective in stopping would-be shooters from committing crimes. “If someone’s decided, ‘I’m going to commit this crime,’ they’ll find a way to get the gun to do it,” said Rubio, who gun control activists protested this week in a campaign inspired by the film “Three Billboards Outside Ebbing, Missouri.”Related:This article originally appeared on HuffPost.
