German Chancellor Angela Merkel is making her farewell visit to Washington DC after nearly 16 years in office, during which time she has worked with four US presidents.
Her tenure ushered in a warm transatlantic friendship, marked by occasional spats over Germany's military spending, climate change and financial recovery policies.
