President Donald Trump warned Thursday that his election opponent Joe Biden wants to destroy "American greatness" in a speech accepting the Republican nomination for a second term against a backdrop of explosive racial tensions and the deadly coronavirus pandemic. The former celebrity realestate developer declared himself all that stands between Americans and the disaster he claimed his "weak" Democratic rival would bring if he wins on November 3. "This election will decide whether we save the American Dream," Trump said. " "Joe Biden is not a savior of America's soul. He's the destroyer of America's jobs and given the chance, he'll be the destroyer of American greatness."
