Now we move to the white house and an awkward telephone call for the president today. Everyone wondering if he got an earful from one of the most powerful leaders in the world, angela merkel of germany asking if the u.S. Was listening in on her private cell phone calls. Martha raddatz on the complaint pouring in from america's friends. Reporter: Like almost everyone else in the modern world, chancellor merkel spends a lot of time on her cell phone. And whether it's righting europe's economy or chatting with family, she assumes it's private. Which is why today's accusation is sparking outrage. German officials today saying they have received information that the chancellor's cell phone may be monitored by american intelligence. President obama was in touch with markel almost immediately. All I can tell you is what the president assured the chancellor that the united states is not monitoring and will not monitor the communications of the chonsler. Reporter: But listen carefully. The white house spokesman's choice of words, "is not monitoring" and "will not monitor," leaves out whether she has been monitored in the past. All this comes after an uproar in france with reports that the nsa swept up more than 70 million french phone calls and texts in just a month. And in mexico and brazil, almost all based on leaks from former contractor, edward snowden. Tonight, obama was supposed to host brazil's president. That was before she cancelled over those accusations the nsa was spying on her. Right now these revelations are clearly embarrassing the u.S. And leaving even our greatest allies a lot less friendly. Thank you so much, martha.
