German Chancellor Angela Merkel accepts Obama invitation amid surveillance spat

German Chancellor Angela Merkel has accepted an invitation to visit the United States, months after allegations that U.S. intelligence had tapped her phone strained relations between Berlin and Washington.

In a call Wednesday, President Barack Obama congratulated Merkel on forming a new government last month and wished her speedy recovery from a recent skiing accident.

Merkel's spokesman, Steffen Seibert, said Obama also invited Merkel to Washington "in the coming months," which she accepted.

Merkel has previously said the relationship between Germany and the U.S. was "put on test" by allegations of massive spying by the U.S. National Security Agency, including on foreign leaders.

The White House has denied that the U.S. is listening in on Merkel's phone calls now, but hasn't ruled out that this happened in the past.
