Former U.S. President Barack Obama and his wife Michelle Obama delivered a one-two punch at the Democratic National Convention on Tuesday night, urging Americans to back 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.

¡°We do not need four more years of bluster and bumbling and chaos. We have seen that movie before, and we all know that the sequel is usually worse,¡± Obama told delegates on Day Two of the Chicago convention.
