Barack Obama locked out of the White House
The world's most powerful man was given an embarrassing reminder that not every door will open for him, even at his own office.
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.
He had cut short the last leg of his trip in El Salvador by a few hours in order to face mounting criticism over his policy on the Libya crisis.
Republican leaders have demanded a full explanation for the decision to bomb Col Muammar Gaddafi's forces and want answers on what the US exit strategy is for the military campaign.
Representative John Boehner, the Speaker of the House and the top Republican in Congress, asked in a letter to the president how Mr Obama would measure success in Libya and whether Col Gaddafi had to depart as leader before the US military involvement ended.
The White House on Thursday rejected criticism of Mr Obama's decision to attack Libya in accordance with a United Nations Security Council resolution, saying he had briefed Congress and the public extensively before military action began.
