CHICAGO (Reuters) -Former U.S. President Barack Obama returns to the national stage on Tuesday night to boost his longtime Democratic ally Kamala Harris in her 11th-hour presidential bid against Republican Donald Trump.

America's first Black president, Obama has thrown his considerable political capital behind Harris as she seeks to make history herself on Nov. 5 as the first woman and first Black and South Asian person to be elected U.S. president.
