Parkland shooting survivor and lead activist David Hogg plans to hold "die-in" protests at two Publix stores on Friday.
The demonstrations stem from the Florida grocery store chain's support for gubernatorial candidate Adam Putman, who is a strong supporter of gun rights and has referred to himself as a "proud NRA sellout."
Publix has recently come under criticism by the survivors of the MSD shooting after the grocery giant allegedly gave Adam Putman more than $500,000 for his campaign.
"Publix where shopping means endorsing an organization that called kids that survived a school shooting soulless," Matt Deitsch, a Marjory Stoneman Douglas High School student, said on Twitter.
Hogg and others have called for the company to pull its endorsement of Putman.
Publix has sought to distance itself from the controversy, saying it did not provide any financial support to the National Rifle Association.
"We regret that some of our political contributions have led to an unintentional customer divide instead of our desire to support a growing economy in Florida," Publix said in an statement. "As a result of this situation, we are evaluating our processes to ensure that our giving better reflects our intended desire to support a strong economy and a healthy community."
