Levinson story 'embarrassing' for the government - Goldman
US media reports have suggested that an ex-FBI agent who disappeared in Iran in 2007 had ties to the CIA.
According to a report by the Associated Press and Washington Post, Robert Levinson was gathering intelligence for a team of CIA analysts who had no authority to run spy operations.
After he disappeared, the CIA reportedly paid his family $2.5m (£1.5m) to avoid a lawsuit.
On Friday, the White House said Mr Levinson was not a US government employee when he went missing.
The BBC's Katty Kay spoke to Adam Goldman, the Washington Post's national security reporter who first reported the story.
