“He will not divide us.”

That’s the phrase Jaden Smith chanted over and over for five hours on Inauguration Day, starting at 9 a.m. in front of New York’s Museum of the Moving Image.

Along with Shia LaBeouf, Smith kickstarted what is set to be a four-year-long live stream of resistance against President Donald Trump’s administration, one that’s already galvanized protests around the country.

Smith and LaBeouf are encouraging others to join the protest effort by repeating the phrase “He Will Not Divide Us” the way they did, for as long as possible. Many have already joined in, with conversations and songs being performed in front of the camera throughout the course of today.

According to a statement on He Will Not Divide Us’ website, the live stream will be available 24 hours a day, seven days a week, for four years.
