London Mayor Hits 'Part-Kenyan' Obama on 'Brexit'

President Obama's visit to the United Kingdom took a sour turn Friday as London Mayor Boris Johnson used Obama's "part-Kenyan" background to dismiss the President's opposition to Britain leaving the European Union.

Johnson penned an op-ed in The Sun slamming Obama's opposition to the possible so-called "Brexit." He painted Obama as at odds with British, repeating a previously debunked story about the President removing a bust of Winston Churchill from the White House when he took office.
