MARGARET WARNER:

Her transatlantic coordinator is 34-year-old parliamentarian Philipp Missfelder. Though their center-right party has long stood by the U.S./German alliance, he's been a blunt critic of NSA surveillance and is now the point man dealing with Washington on tough issues facing the two allies.

We spoke this morning in the parliamentary office building in Berlin.

Philipp Missfelder, thank you for having us. Congratulations on your new job.

PHILIPP MISSFELDER, German Coordinator for Transatlantic Cooperation: Thank you very much.
