Students who survived the recent mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, have been putting pressure on big corporations to sever ties with the National Rifle Association, and celebrities are following suit.
"#BoycottNRA" began trending on Twitter overnight Thursday into Friday, with many people tagging specific companies associated with the gun lobby. As of Friday afternoon, the social media movement had inspired several companies to cut ties with the association, including Best Western and Wyndham Hotels, Symantec security software, home security company Simplisafe, Enterprise Holdings, Inc. -- which owns Enterprise, Alamo and National Car Rental -- and First National Bank of Omaha. As of now, Amazon, FedEx, Avis and Hertz still have deals with the NRA.
