Artists from across the country have teamed up including Shepard Fairey, Nekisha Durrett, Nate Lewis, Rafael Lopez, Robert Russell, Rob Sheridan, and Swoon (Caledonia Curry) to create striking anti-Trump posters and billboards in several battleground states. The #RememberWhatTheyDid campaign is the brainchild of Robin Bell, known for projecting videos onto the Trump Hotel in Washington D.C., and Scott Goodstein, who worked on the campaign of Barack Obama and Bernie Sanders. More than 40 of the billboards will go up in Detroit, Lansing, Flint, Grand Rapids, and Kalamazoo. Here's a look at some of the ones that are already up.
