Washington | President Donald Trump on Sunday retweeted a video of one of his supporters yelling "White power!," once again using the vast reach of his social media platforms to inflame racial divisions in a nation roiled by weeks of protests about police brutality against Black people and demands for social justice reforms.

The edited racist video shows a white man riding in a golf cart bearing "Trump 2020" and "America First" signs during what appears to be an angry clash over the President and race between elderly white residents of a Florida retirement community.

The two-minute video continues to show profane exchanges between protesters and other Trump supporters riding on more golf carts.

The President retweeted the video to his millions of followers just after 7:30 Sunday morning, thanking "the great people of The Villages", the Florida retirement community where the clash apparently took place.

John Bolton, the President's former national security adviser who just released a scathing book about Trump, said on Sunday that the President's inattention to detail made it possible that he did not notice the racist comments.

"It's entirely possible that he tweeted this video because he saw the sign; I think it was in the first go-kart that said the Trump 2020 or something like that.

The video — which could not be independently verified by The New York Times — appeared to show a slow-moving parade through the Florida community with supporters of Trump riding golf carts, wearing red, white and blue, and displaying pro-Trump materials.
