Timing of US president's Argentina visit criticised

After his historic visit to Cuba, President Barack Obama is now in Argentina, where he will be meeting President Mauricio Macri - the first bilateral visit by a US president in 19 years.

What was initially meant as a trip focusing on economics and trade has become controversial because of its timing. It coincides with the 40th anniversary of a coup that installed a bloody military rule.
