US President Barack Obama made his farewell speech in Chicago today as he closes the book on his presidency. Chicago is his adoptive hometown, where he has addressed a sold-out crowd, not far from where he accepted presidency eight years ago. Barack Obama's final speech as president was also his last chance to try to define what his presidency meant for the US. Reports say the outgoing US president had asked his team to craft a speech that would feel "bigger than politics" and speak to all Americans - including those who voted for president-elect Donald Trump. "For Michelle and me, Chicago is where it all started. It's the city that showed us the power and fundamental goodness of the American people," President Obama had said in a Facebook post previewing his remarks, adding "I'm returning to where it all began to offer my most grateful farewell to the American people. I hope you'll join me - I want to thank you for everything you've done."
