The President said he wanted the UK to stay in the EU as he wants Britain - and David Cameron - to have a strong voice at the top table of world affairs.
If right now I've got access to a massive market where I sell 44 per cent of my exports and now I'm thinking about leaving the organisation that gives me access to that market and that is responsible for millions of jobs in my country and responsible for an enormous amount of commerce and upon which a lot of businesses depend ... that's not something I'd probably do.
