David Hogg, Marjory Stoneman High School shooting survivor and student advocate, is urging people to boycott two major investment firms, Vanguard Group and Blackrock, over their ties to weapons manufacturers.
On Thursday, Hogg suggested contacting employers that use Blackrock and Vanguard for their 401(k) retirement accounts to broaden the boycott.
Blackrock and Vanguard Group own large percentages of Weaponsmakers, Sturm, Ruger & Co. and American Outdoor Brands.
While the companies did not directly address Hogg's proposed boycott, Vanguard said it offers customers funds that do not include gun makers. Blackrock said it plans to do so.
Hogg and other MSD students have become advocates for more regulations on weapons since a mass shooting at their school on Feb. 14 left 17 people dead.
While Republicans in Congress have rejected calls for more federal regulations on guns, the students and other gun control activists have found success lobbying corporate America to distance itself from the National Rifle Association.
Hogg, who has more than 700K followers on Twitter, recently spearheaded a successful boycott advertiser boycott of Laura Ingraham after the Fox News show host mocked Hogg on social media.
Dozens of advertiser pulled out of the show despite Ingraham making a public apology. Fox News said it stands by Ingraham.
