Barack Obama's half-brother, Malik Obama, launched a nasty rant on Twitter against the US President, just moments before the third and final presidential debate between Democratic Party candidate Hilary Clinton and Republican Donald Trump in Las Vegas, Nevada.

Malik, who is the older of the two, took to the social media platform, where he threw shade to the president, criticising him on personal and political issues. In almost half an hour, Malik shocked the world with his tirade, as he went as far as questioning whether Barack was indeed his brother.

In a bid to prove whether the two were siblings, the agitated Malik even offered to take a DNA test and challenged Barack to do the same. This guy!!

In one of the many bitterness-filled tweets, he claimed that at some point, First Lady Michelle Obama made him sleep at a hotel. Kwani alidhani White House ni some grass-thatched mud house somewhere in Kogelo?!!!

However, Malik was savagely bashed on the same platform with some 'go f*ck yourself' suggestive comments.
