The two world leaders were on the same side on the Brexit issue.
Cameron was known supporter of the European Union, commonly known as the EU. During his resignation speech Cameron said, “I was absolutely clear about my belief that Britain is stronger, safer and better off inside the EU.”
President Obama sided with Cameron’s belief and during a press conference stated, “The European Union doesn’t moderate British influence -- it magnifies it. A strong Europe is not a threat to Britain's global leadership; it enhances Britain’s global leadership.”
Cameron will stay on as prime minister until the fall. He did suggest a new leader be selected and in place by the Conservative’s party that takes place in October, according to The Guardian.
