LaBeouf, along with artists Nastja Säde Rönkkö and Luke Turner, erected a "He Will Not Divide Us" flag in a field in Greeneville in March after the project was moved from New York City and Albuquerque.
The project, called HEWILLNOTDIVIDE.US, was launched in New York City on Trump's Jan. 20 inauguration date and featured a 24-hour live web stream outside the Museum of the Moving Image, where participants could recite the phrase into a camera.
Once it reached Greeneville in early March, where LaBeouf, Rönkkö & Turner planned to fly the flag for the duration of Trump's presidency, the project had become a live stream simply showing the flag and sky behind it. The group had not disclosed the flag's location.
But in the early hours of March 10, Turner said, the flag was stolen. The video stream showed the "He Will Not Divide Us" flag coming down — though it didn't picture the perpetrator — and a red "Make America Great Again" ball cap and pro-Trump T-shirt being raised in its place, said Rachel Bewley, who owns the property.
The T-shirt depicted Trump as Pepe, an animated frog frequently used in racist memes online by members of the so-called "alt-right."
