President Obama lookalike Louis Ortiz has told the BBC that he is happy that the president has been re-elected because it secures him "at least four more years of work".
Hundreds of thousands of supporters gathered to see the real Mr Obama be sworn in by Chief Justice John Roberts in Washington DC.
Khalil Senghori, an Obama supporter, told the BBC's Laura Trevelyan that the atmosphere on the Mall was "wonderful".
