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 Americans 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. Mr Trump deleted the tweet more than three hours after posting it.
