Pictured: Obama's half-brother wearing Hamas scarf that boasts 'Jerusalem is ours – WE ARE COMING'

During a 2010 event in Yemen, President Obama's half-brother Malik wore this Hamas keffiyeh featuring the slogans 'Jerusalem is ours -- WE ARE COMING!' and 'From the River to the Sea'

Malik Obama was the best man at the 1992 wedding of Barack and Michelle Obama

The photo appears on the website of the Barack H. Obama Foundation, a group that Malik founded and manages, despite its lack of a connection with he U.S. president. The name in the organization's title refers to the president's father, the parent whom the two men share in common.

Malik Obama has been a visitor to his half-brother's Oval Office in the White House, and also appears to be a die-hard supporter of the Hamas terrorists

In 2004 when the president first ran for election to the U.S. Senate, his half-brother Malik showed off a photo of himself in Kenya with Barack Obama (L in photo)

His first foray into politics ended badly when he was trounced in a regional governorship election in 2013, despite using a photograph of him and President Barack Obama in the Oval Office as his political calling card.
