7:52 PM - Obama's Half Brother Supports Trump
Malik Obama, a Muslim with Kenyan and US citizenship, also told the BBC that the Republican presidential nominee's proposal for a temporary ban on Muslims entering the US was "common sense".
Mr Trump's plan - pitched as a security measure - has been widely condemned.
Malik Obama has accused the president of turning his back on his family.
He told the BBC's Newsday programme it was "sort of disappointing, somewhat hypocritical" that no representatives of the Obama family from Kenya were attending the Democratic convention, taking place in Philadelphia.
The president, he said, had "made a big deal about his heritage... and now it's a complete blackout".
