Germany wants answers on allegation the National Security Agency spied on Chancellor Angela Merkel.
German officials were in Washington Wednesday meeting with President Barack Obama's counter-terrorism and national security advisers, including Director of National Intelligence James Clapper.
They brought with them a strong message for the administration: "Never spy on your friends," Elmar Brok, a German member of the European Parliament, said.
Just yesterday Clapper was on Capitol Hill testifying on the NSA tactics. He maintains spying on allies' leaders is a longtime practice in the intelligence world.
We do not spy on anyone except for valid foreign intelligence purposes," Clapper said. "And we only work within the law."
