Barack Obama locked out of the White House

President Barack Obama was filmed being confronted by a locked door when he tried to enter the Oval Office from a terrace at the White House as he returned early from a trip to Latin America.

With a nonchalant stroll and a whistle, the US president walked past another set of locked French doors before he was finally able to gain access to his seat of power.

White House staff members were reportedly not informed before his arrival on Wednesday evening that the president was returning to work.
