US President Barack Obama told Britons on Friday he loved Winston Churchill, rebuffing suggestions that he had disrespected the wartime leader because of a grudge against Britain linked to his Kenyan ancestry. Obama was visiting London to press Britons to vote to stay in the European Union, and the Churchill issue arose after London Mayor Boris Johnson, who is campaigning for an "Out" vote, brought it up in an article criticizing Obama. "I love Winston Churchill, I love the guy," Obama said when asked at a news conference about Johnson's article.
