Obama Spy Chief: You Talkin' to Me?

He's the Director of National Intelligence for the president, but James Clapper was dumbfounded when asked, after a day of news coverage, about the terror arrests in London.

US Director of National Intelligence James Clapper was asked about the attacks, with ABC News interviewer Diane Sawyer posing the questions: "First of all, London. How serious is it? Any implication that it was coming here?"

After a long pause, Clapper replied, "London?"

Despite protective efforts by Terror Adviser John Brennan, Clapper admitted he was ignorant of the story.

Sawyer brought up Clapper's apparent ignorance of the developments later in the interview.

"I was a little surprised you didn't know about London," she said.

"Oh, I'm sorry, I didn't," Clapper replied.

Lame attempts to do damage control followed.

Between the interview's filming Monday and airing a day later, the office of the Director of National Intelligence (DNI) issued a statement, insisting the "question about this specific news development was ambiguous."

"The DNI's knowledge of the threat streams in Europe is profound and multi-dimensional, and any suggestion otherwise is inaccurate," said the department.
