Florida Republican Sen. Marco Rubio has received $3,303,355 in donations from the NRA. Sarah Chadwick, a survivor of the Florida Stoneman Douglas High School shooting, tweeted: We should call AR-15s "Marco Rubio" because they're both so easy to buy. I decided to help Sarah by designing and coding a chrome extension that replaces the text 'AR-15' with 'Marco Rubio' on any website.
