The video already has five million views
U.S President Donald Trump is being heavily criticised for releasing a Republican advertisement on his official Twitter page.
The video was posted five days before the American midterm elections and is being perceived as racist for its extremely negative portrayal of immigrants in America.
It shows a man in a courtroom who is bragging about having murdered policemen, and also shows him claiming that if he gets the chance he will do it again.
It then shows the words: "Who else would Democrats let in?" flash across the screen.

CNN described the video as "the most racially charged national political ad in 30 years".
They doubled-down on their criticisms of the video, saying: "The Trump campaign ad is the latest example of the President's willingness to lie and fear-monger in order to tear at racial and societal divides; to embrace demagoguery to bolster his own political power and the cause of the Republican midterm campaign."
The video is being compared to one that was released by George Bush's campaign during the 1996 election, which was was said to have used racist imagery.
