US intelligence officials have denied German newspaper reports that Barack Obama was briefed by National Security Agency (NSA) chief Keith Alexander about Angela Merkel's phoned being tapped.
NSA spokeswoman Vanee Vines said:
[General] Alexander did not discuss with President Obama in 2010 an alleged foreign intelligence operation involving German Chancellor Merkel, nor has he ever discussed alleged operations involving Chancellor Merkel.
News reports claiming otherwise are not true.
