New York, Jan 21 (IANS): Actor Shia LaBeouf has launched a four-year livestream in protest against President Donald Trump.

As Trump took the oath of office to become the 45th President of the United States, LaBeouf, collaborators Nastja Säde Rönkkö and Luke Turner, and Jaden Smith called on the public to take another oath: "He will not divide us".

The "He Will Not Divide Us" title of a participatory livestream was unveiled by the performance artistes on Inauguration Day on Friday, reports usatoday.com.

Staged outside New York's Museum of the Moving Image, the public art project invites passersby "to deliver the words 'He will not divide us' into a camera.

According to the livestream site, "the mantra 'He will not divide us' acts as a show of resistance or insistence, opposition or optimism, guided by the spirit of each individual participant and the community."

Smith became the first guide for the project, reciting the mantra for three-plus hours in front of a growing crowd. "He Will Not Divide Us" will stream "continuously for four years, or the duration of the presidency".
