Immediate former US president’s half-brother Malik Obama has once again sparked a row over the former US Presidents birth certificate by suggesting he was born in Kenya.

Malik Obama, an avowed Donald Trump supporter, posted on Twitter a picture of a document that alleges his brother was born at 'Coast Province General Hospital’ in Mombasa.

Malik Obama tweeted a copy of what he claims is a valid birth certificate proving that his half-brother was born in Mombasa, Kenya.

The 'birth certificate' bears the letterhead of the 'Coast Province General Hospital' in Mombasa.

In 2009, a man by the name of Lucas Smith offered the document for sale on eBay.

The website eventually removed the page because it has a policy of barring its users from selling purported government documents.

The certificate indicates that a male child called Barack Hussein Obama was born on August 4, 1961, and his parents are stated as Ann Dunham and Barack Obama Snr - his real parents.

Dan Branch, a British professor in African history at the University of Warwick, noted that at that time Kenyan provinces were referred to as “regions."

The older Obama has had a frosty relationship with his brother.

Malik in 2008 opposed then senator Obama’s candidature for the US presidency.

Last year, Malik accused the former US president of ignoring his Kenyan family and the African continent after he was elected the first black president of the US. Obama, however, used his Kenyan roots as a strong pillar of his 2008 presidential campaigns.

“President Obama is my brother and I love him, but he is a hypocrite because he has neglected his African heritage and wants nothing to do with it despite campaigning on a platform that he will help transform Africa,” Malik said.
