Malik Obama has reportedly accepted Republican presidential nominee Donald Trump's invitation to be his guest at the debate, Mediaite reported.
The president's brother has previously publicly supported Trump's bid for the White House and expressed anger at not being invited to the Democratic National Convention.
He told the BBC it was 'sort of disappointing, somewhat hypocritical' that no members of Obama's Kenyan family attended the DNC this summer.
Malik will be seated next to Trump's other guest Pat Smith, the mother of Sean Smith who died in Benghazi.
Pat Smith spoke at the RNC over the summer.
Along with inviting his guests to try and throw Clinton off, Trump mocked her during a campaign.
'She's home sleeping and I'm working. That's the way it's going to be in the White House, too. She'd be sleeping. I'd be working,' Trump told a crowd in Colorado on Tuesday afternoon.
Clinton is also inviting guests to Wednesday night's debate that have rocky pasts with Trump.
