Barack Obama is no longer president, but the birther movement alleging that he was born abroad still lives – thanks to his half-brother.

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 sex of the baby is male, and the date of birth is listed as August 4, 1961, which is the former president's genuine birthday.

The 'document' also lists the names of Obama's parents, Barack Hussein Obama and Stanley Ann Obama (née Dunham).

The issue of Obama's birth as well as his religion have been frequently discussed matters within right-wing circles and conspiracy theorists.

The unfounded rumors of Obama's country of origin were largely meant to call into question the legitimacy of his presidency.

The US Constitution does not permit citizens who were born abroad to attain the presidency.

During Obama's years in the White House, President Donald Trump frequently promoted the conspiracy theory alleging that Obama lied about being born in Hawaii.

He has also accused his half-brother of not doing enough to help his family

During Trump's presidential campaign, the candidate publicly acknowledged that Obama was born in the United States – and then blamed his Democratic opponent, Hillary Clinton, for initially disseminating the birther claim.

Malik Obama is a resident of Kenya and a naturalized US citizen. It is estimated that he has between three and 12 wives thanks to Kenya's legalization of polygamy, according to The Washington Post and CNN.

Last July, Malik Obama told the New York Post that he would be supporting Trump.

In an interview from his home in Kenya, Malik Obama said he was voting for the Republican candidate because 'he speaks from the heart.'

The former Democrat voter said he was voting for a Republican after feeling 'deep disappointment' at his half-brother's presidency.

Trump was apparently so impressed with Malik Obama's expression of support that he invited him as his guest to the presidential debate against Hillary Clinton in Las Vegas on October 19.

The Obama brothers have had a strained relationship over the years.

They first met around 30 years ago and were best men at each other's weddings. Malik claims that he's been invited to the White House on numerous occasions and that he stays in contact with the president.

'Of course we're close!' he told GQ in 2013. 'I'm the one who brought him here to Kogelo in 1988! I thought it was important for him to come home and see from whence his family came – you know, his roots.'

Malik told MailOnline that year that his more famous half-brother is 'always at the end of a phone line if I want to talk.'

Trump gladly accepted Malik Obama's endorsement and used it to chide Barack Obama for 'treating him badly - like everybody else'

Meanwhile, Malik has previously chided Barack for not doing enough to help his Kenyan relatives.

'I'm very proud of my brother, but I would like for him to do a little bit more for the family on this side. I would like to say he could send some money. I give money when asked. That's what family is for. We're not well off, though people think we are.'

He also said that the president did little to help his own foray into politics when he unsuccessfully ran for governor of the southwestern Kenyan county of Siaya in 2013.

'I don't think politics is my thing,' he told The Post. 'Honestly, I'll be happy when my brother is out of office, and I will finally be out of the limelight and be able to live like a human being.'

It has been speculated that Malik Obama is also angry with his brother for his actions in Libya.

The Obama administration supported the removal of former Libyan ruler Muammar Gaddafi, whom Malik Obama has described as a friend of his.

Malik Obama was initially vilified by pro-Trump elements in the media because of his alleged past support for terrorist groups like Hamas, according to Media Matters.

But when Malik Obama began to speak publicly about his rift with Barack, attitudes toward him on the right changed.

Not only did Malik Obama embrace the birther movement, but he also told Joel Gilbert that Obama's real father was a prominent communist named Frank Marshall Davis - another unfounded conspiracy theory that has been floating around on the internet.

Meanwhile, Malik Obama has been described as an opportunist who has asked journalists for thousands of dollars in exchange for the privilege of interviewing him, according to Vox.
