ROUGH CUT (NO REPORTER NARRATION) STORY: President Barack Obama painted an optimistic picture of America's future in a speech on Wednesday aimed at giving full-hearted support to Hillary Clinton to help her defeat Republican rival Donald Trump and become the first woman elected U.S. president. Obama fought back against some of Republican presidential nominee Donald Trump's rhetoric about making America "great again." "America is already great, America is already strong, and I promise you, our strength, our greatness, does not depend on Donald Trump," Obama said to cheers. The Democratic president also laid out what he said were a series of advances during his two terms in office, such as recovery from economic recession, the Obamacare healthcare reform and the 2011 killing of al Qaeda leader Osama bin Laden. Clinton made history on Tuesday when she became the first woman to secure the presidential nomination from a major party. When she formally accepts it on Thursday, she will become the Democratic standard-bearer against Republican nominee Trump in the Nov. 8 election. At the convention on Wednesday, U.S. Senator Tim Kaine accepted the Democratic vice presidential nomination. Obama and Clinton were rivals in the hard-fought campaign for the 2008 Democratic nomination. After winning that election, he appointed her his secretary of state.
