The US President Donald Trump on Sunday retweeted a video of one of his supporters yelling White Power, once again using his social media platforms to inflame racial divisions.

Iran PressAmerica: This is while most of the states of America have been 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 white residents of a Florida retirement community.

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

The tweet was widely criticized as racist and insensitive, and again demonstrated the president’s willingness to use social media to amplify some of the most hateful comments of some of his followers, even at a moment of national unrest.

Senator Tim Scott of South Carolina, the only black Republican senator, called the video “offensive” and asked Trump to take it off his Twitter page.

"There is no question he should not have retweeted it, and he should just take it down," Scott said on the CNN program "State of the Union." "We can play politics with it or we can’t. I’m not going to. I think it’s indefensible. We should take it down."

Trump deleted it less than an hour after Mr. Scott’s comments, but he did not condemn the "White Power" statement or specifically disavow the sentiment expressed by his supporter.
