In photos: Biden's first trip abroad as president

A security officer asks the media to step back at the start of Biden's summit with Putin. There was a chaotic scrum of reporters from both countries during the photo op, and the situation got incredibly tense between the two traveling press corps, according to CNN Chief White House Correspondent Kaitlan Collins. Reporters were seen blocking cameras as the two presidents were trying to give their opening remarks to each other. Sitting with the presidents here are US Secretary of State Antony Blinken, left, and Russian Foreign Minister Sergey Lavrov.
