Last month in Emma Gonzalez’s powerful anti-gun rally speech, the 18-year-old Marjory Stoneman Douglas high school student cited that the National Rifle Association’s donation to Donald Trump, and divided that by each student killed in the past 18 months — it equates to roughly $5,800. This is part of the reason students in today’s March For Our Lives gun reform protest are wearing price tags on their bodies, with the price tags also pointing to the number of donations Florida Senator Marco Rubio received from the NRA.

Rubio reportedly received $3,303,355 from the NRA, and dive that by the number of students in Florida, that equates to each student being worth $1.05. These free printable price tags are available on the March For Our Lives website, and protesters are encouraged to wear them. “On March 24th wear this price tag to protest politicians who accept NRA blood money and demand they pass meaningful gun control legislation now,” the site reads.

Fellow Marjory Stoneman Douglas student Sarah Chadwick explained in her speech at today’s rally that that $1.05 would equate to the 17 students killed in the Parkland high school’s massacre being worth less than $20. “Is that all we’re worth to these politicians? A dollar and five cents? Was $17.85 all it cost you that day, Mr. Rubio,” Chadwick demanded. “Well I say, one life is worth more than all the guns in America.”

The Nonpartisan Center For Responsive Politics estimated that the NRA spent $54 million securing Republican control of the White House and Congress in the 2016 election. Of that money $30.3 million went to electing President Donald Trump.
