Germany has information that the United States might have monitored Chancellor Angela Merkel's cell phone, a German government spokesman said Wednesday.
"We have immediately sent a question to our American partners and have asked for immediate and wide-ranging clarification," spokesman Steffen Seibert said in a written statement.
Both governments said that Merkel spoke about the issue with President Barack Obama during a phone call Wednesday.
Obama told her that the United States "is not monitoring and will not monitor" her communications, White House spokesman Jay Carney said.
Merkel made it clear that, if the information about the U.S. having monitored her phone were true, it would be "completely unacceptable," Seibert said.
“The White House did not specify, however, if such monitoring had taken place in the past,” reports CNN’s Jim Sciutto.
