“The US government is refusing to grant Angela Merkel access to her NSA file or answer formal questions from Germany about its surveillance activities, raising the stakes before a crucial visit by the German chancellor to Washington. In October, Obama personally assured Merkel that the US is no longer monitoring her calls, and promised it will not do so in the future. However, Washington has not answered a list of questions submitted by Berlin immediately after Snowden’s first tranche of revelations appeared. Angela Merkel has defended the decision to keep access to the Stasi archive open to German citizens, and has reportedly used the opportunity to view her own Stasi file in person.”
