President Obama has ended his historic trip to Cuba. It was the first time a U.S. president had visited the island nation in almost 90 years.
During his time there he held a joint press conference with Cuban leader Raul Castro, a rare event for the communist country. President Obama was also informed of the terror attacks in Brussels during his visit to the island. President Obama is now in Argentina for a two-day trip.
Here is a look at some behind-the-scenes photos posted on Instagram by Chief Official White House Photographer, Pete Souza.
