Donald Trump defends calling Barack Obama IS founder

Republican presidential candidate Donald Trump defended his decision to label US president Barack Obama the “founder” of Islamic State (IS).

He also called Democratic nominee Hillary Clinton a “co-founder”, igniting fresh criticism of his inflammatory campaign style.

Asked in an interview with CNBC whether it was appropriate for him to call the sitting president of the US the founder of a terrorist organisation that wants to kill Americans, Mr Trump reaffirmed his accusation.
