Donald Trump admits President Obama was born in US

Republican presidential nominee Donald Trump has finally acknowledged that President Obama was born in the US.

Speaking at a news conference, Mr Trump tried to blame Democratic rival Hillary Clinton for the so-called the "birther" movement that questioned Hawaii-born Mr Obama's citizenship.

The "birther movement" is a conspiracy theory that Mr Obama was actually born in Kenya and is therefore ineligible to be president.

Reports in various US publications suggest it was circulated in 2008 by die-hard supporters of Mrs Clinton as it became clear that she was not going to win the Democratic nomination.

However there is no evidence that Mrs Clinton or her then campaign had anything to do with it.
