Former U.S. president Bill Clinton has formally placed President Barack Obama's name up for the Democratic nomination during a nationally televised address Wednesday.
Mr. Clinton fired at the Republican party during his prime time speech at the Democratic National Convention, calling the Republican narrative an "alternative universe."
Mr. Clinton remains a popular figure among many Americans who recall the economic prosperity during his two terms in office in the 1990s.
The DNC aimed to strike at Mr. Romney's record as a businessman, which Mr. Clinton called "sterling" earlier this year.
Among the speakers Wednesday were three employees that were fired from companies controled by Bain Capital, an asset management firm that Mr. Romney co-founded and ran as CEO for several years. One of the employees said America cannot afford "Romney economics," which he said was "putting profits before working people."
