President Obama's speech on security and privacy reforms were "embarrassing", Wikileaks founder Julian Assange has said.
Mr Assange, who has been inside the Ecuadorian Embassy in London for more than a year to avoid extradition to the US told CNN: "I think it's embarrassing for a head of state to go on for 45 minutes and say almost nothing.
"It's clear that the president would not be speaking here today if it were not for the actions of Edward Snowden and whistleblowers before him...these whistleblowers have forced this debate. This president has been dragged kicking and screaming to today's address", he added.
"Unfortunately today we also see very few concrete reforms".
