With all the stress of the first Presidential debate on Wednesday night, Barack Obama still did not forget another important occasion on October 3rd - his 20th wedding anniversary.

Ever the modern couple, Barack and Michelle Obama tweeted each other anniversary greetings, with the President including a picture of him and his wife on their wedding day.

Instead of a cosy anniversary dinner, Obama will spend tonight in the cold hall at the University of Denver, where he will take on Republican opponent Mitt Romney at 9 pm US time (2am in the UK).
